Not the best, but worth a try to see if trackers are your thing before investing more

Get what you pay for.  Bought for my husband, and he was reluctant to go to more expensive, familiar brand product.  Inconsistent performance, but OK for starter tracker.  Will upgrade if he finds having a tracker useful

The cadence feature on this unit was unreliable for the first couple week after installation. Even now I must fiddle with the sensors sometimes to keep it working. Recently, it seems to have settled down, though. Basic and cheap is the appeal hear, I wish the display was bigger and I like more options for the combination of read-outs that can be shown at once. But the main reason I gave it only 3 starts is that I am not yet confident the cadence tracker is reliable. I also find it difficult to remove from its holder.

Consider this a semi-sleep tracking device. Unless you tell it by pressing a button if you are asleep or awake it will keep logging for days of sleep. Steps are a hit or miss also. But since I used more expensive devices before they did not fare that much better either, even at 10 times the cost of this one. If nothing else it's a watch. Ain't worth returning it as someone else noted before.

PROS:
Great way to get the notification aspect of a smartwatch without the high price tag
Not super-attractive, but not bad looking for the price
Vibration on the watch means that you can catch a notification even if your phone is in silent mode across the room
Custom vibration patterns so you can tell what type of notification it is before you look
Disable notifications from apps you don't want to see on your watch
Decent battery life - I usually get close to a week before needing to charge
A limited number of silent alarms can be programmed for specific days and times
Other features like a low flashlight, camera shutter control, etc. are a bonus

CONS:
NO WARRANTY unless seller is on their authorized reseller list - don't buy off of Amazon and expect coverage unless Amazon is the listed seller on your order
Fairly large watch body
Bezel around face of watch is not attached well - it fell off repeatedly and, despite my attempts to glue it back on, it finally got lost and I had to get a replacement
App is a little rough around the edges, and fails to properly retrieve the names of several apps, making the customization difficult
After eight months of use, my watch has begun shutting off constantly even after charging overnight

CONCLUSION:
While the idea is great, and the price won't break the bank, the build quality was disappointing and the loss of all functionality except analog time-keeping after such a short time makes me regret the purchase. I'd recommend saving your money and putting it toward a fitness tracker with notification support, an actual smartwatch, or just a regular dependable analog watch (because in a few months, that's all you'll have anyway).

So first and foremost, if you order the mi band, get it from Ranphy. It'll take 5 days to arrive but it is definitely not the knock-off. It's an actual Mi Band... Not a day day.

Second, I know what you're thinking. "I can bypass the $150 entry to a Fitbit and get this cheap Mi Band." Well you're right and you're wrong.

It's definitely most of what the other activity bands are. It syncs reasonably well and gets killer battery life. It tracks steps, sleep, distance and weight if you enter it manually or buy the matching scale.

Buuuut it seems like it's easily fooled. Flipping a page on a book seems to make it think I took a step. And I don't trust the sleep tracking either. I have terrible sleep patterns and it seems to think I'm sleeping better than I am. I bought it mostly as an alarm, but you can hardly feel the vibration (if it even vibrated this morning. I'm not sure it did).

And that's the only problem with the Mi Band. It likes to go passive and sync sporadically unless you open the app. So I have a feeling it doesn't even set the alarms off unless you've recently opened the app and synced.

All in all it's cheap and gets the job done. If you want to track steps and distance, get it. Works great. If you want alarms, reliability and dependability, then it's up to you to see if you can live with this thing.

It has routed me through shopping center parking lots and took me to the back side of the Best Buy store. When I thought it was off track, it was just taking me to the back of the store. I'm no GPS expert, but it seems to have decent features and accuracy for the price. It's a small screen, but has decent detail and accuracy. I was a little disappointed in some if it's selections regarding shopping and restaurants. Hard to believe it has all the information in that is does.

The biggest downside of this product is that dogs don't have cell phones.  This means that the tracker needs to have built in cell service, and because of that there is a monthly fee.  $6.95 is the cheapest (with a 2 year contract I believe, otherwise $9.95 a month).

The added benefits are supposed to be tracking your dogs activity, location, wether they leave a certain zone, and a few other items surrounding this.  While they do work, it's more of a gimmicky thing,as sometimes they do not work.  That means you can't always rely on them.  The other downside is that you need to charge the battery every so often, which is just another thing to remember (they say 10 days, but it's not quite that much).

Fitness trackers are becoming increasingly popular, and while a lot of the fitness trackers on the market today have similar features such as a pedometer to track the number of steps you've taken in a given day, or a heart rate sensor to determine your current heart rate at any given point, a lot of those have one thing that is very similar and that is that they require you to be moving a lot to see any results. This activity tracker is a bit different because the main focus of it instead of constantly moving  is on your breathing and what that can actually do for your body. For example, with this tracker if you are currently stressed out then you'll be able to notice on the mobile app that your breathing levels are very different then from when you are calm. The application when paired with this activity tracker will pulse (vibrate) to let you know that you are stressed out and you should try and take slower, deeper breathes to try and calm yourself down. It sounds very gimmicky and not needed but it is actually very impressive and helpful once you get to using it.

The application is available on Apple and Android devices and should work with any phone or even tablet. I did notice a lot of people pointing out that for Android the application gets stuck on the "loading" portion and then freezes up which makes this device effectively useless but I personally did not experience this problem on my phone and it loaded up right away. Once you're in the app you'll notice that there is a few sections for you to add information about your current health such as your height and weight. You can skip this but the application will be much better suited to your needs if you do input this information so I do suggest it.

You're able to clip the tracker in a few places on your body, just give a few spots a try and see what works best for you. There is a ton of options to play around with in the application and I highly suggest spending a good 15 minutes just exploring all of the features to get a better hang of the device. Overall, I am very impressed with this activity tracker. I am a pretty relaxed person overall but I've already made a few adjustments to my daily life style thanks to the constant tracking of my breathing with this tracker.

Pros: The biggest pro is the low profile -- you don't feel like you've got a clock strapped to your wrist. The step counter seems pretty accurate and, if you accurately measure your walking and running stride lengths and enter them into the custom settings, your distances will be nearly spot-on for those activities. Charging is easy and relatively fast.

Cons: I haven't been able to properly sync my activities to the Garmin software (Garmin Express and Garmin Connect) for months. Basically, when I sync, only the single latest activity since the last sync will be recorded on Express and Connect.  So if I've done 4 runs and 3 walks since the last sync, the software only picks up the last activity. This seems to be an issue with a number of users over the past couple of years. I've scanned the various troubleshooting boards and tried many solutions (religiously updating, reinstalling devices, removing specified files from the software, etc.) to no avail.

Conclusion: If you're looking for a device that accurately records your every activity, this may not be for you. If you want something light on your wrist and fairly accurate, but don't much care about record keeping, it's a nice device.  Despite the software annoyance, I do like this tracker.

PROS:
- Free cloud storage
- Good picture
- Friendly app
- Reliable night vision (better than the Pro)

CONS:
- The battery is the weak link here.  They claim it will last 4-6mos, but like your phone battery, usage is going to cut that down.  I lost 8% just getting it set up and oriented (positioning, testing sensitivity, etc).  The painful re-syncing process (see below) cost me another 11%.  I lost 2% in the few days I tested.
- You cannot recharge the batteries as-is.  You will need a charger, purchased separately.  If you don't want a big gap in surveillance, you'll need another set of batteries.  A charger and the batteries they recommend will run you about $40-50.
- Will not continually record when there is motion. You can set a duration when there is motion (5-120sec), but it will not necessarily make a new recording when the recording end, even if there is still motion. I tested on a 5sec limit, walked out of the house and to the sidewalk, counted to five, and walked back.  On my exit was captured.  It cannot turn around uploading even a tiny video fast enough for contiguous capture.  My advice, max it out to 120sec, and hope for the best.
- Added to the above is the annoying thing that there IS a button to turn off duration and have it record all motion, but you can't turn it off.  Support confirmed it did work, but they disabled it because they couldn't get it to work right.
- The packaging is a hassle.  They have the cam in this clear top-box.  I needed some pliers to dislodge the camera from the bottom box.
- The network activity on these is ballistic. Not so much bandwidth, but my TrendNet switch is constant yellow for all the collision activity the base unit produces.
- Set-up is a fickle mistress.  I got it synced very quickly the first time, but while trying to troubleshoot something with support, they managed to break it, and not get it back the way it was.  After 2-3 hours of endless retrying things on my end on my own, I got it finally working again.

Overall, I like the device on the whole.  If I didn't opt for the Pro (not without it's list of issues), I would have kept it.

On a side note to Netgear, they follow-up note to my post seems nice, but it's a pretty empty gesture. I tried posted a level-headed note in the tone of this review on their Facebook page, but they censor any negative posts there. Their posture strikes me as more PR facing, then genuinely caring about what consumers have to say.

App was too difficult to use, and I'm pretty savvy with that sort of thing. As a tracker throughout the day, works great. Great watch too. But I need to be able to look at my progress over a longer period.

This device serves as a robust watch, an average step counter, and a below average heart-rate monitor. The heart-rate monitor only checks your HR momentarily. It does not constantly check like other HR bands. The plus is that this significantly adds to the battery life. The step counting is not as accurate as your smartphone, but for $30 it's hard to complain that it doesn't recognize your steps while your pushing a cart it or your arm isn't in motion. The band is light-weight and not too bulky. The app is okay, but not better than the fitness apps on your phone (again for $30, you get what you pay for here). I have only had this device for a week and am hoping that it lasts longer than my previous fitbit band.

My Watch arrived on Sunday, (10-23-16) and the first thing I did was charge it fully. Then I got out the instruction sheet to set up the watch. Unfortunately, the font size is about a 6 font and I needed a magnifying glass to read it. You will need to download the app in order to set up your watch and use the tracking features. It really wasn't hard to get the watch synced to the app. (I have an LG4) For those of you that said you cant get it off military time.. go to the app settings and shut off the 24-hour option, now your watch will keep 12hr time. Also, there are replacement bands available- which I ordered a three pack that has the red, black and blue bands so I can color coordinate if want.

The pros:
Its comfortable to wear
It keeps accurate time as it is synced to the app on your phone/laptop
It gives you a general idea of how many steps you walk
It gives a general idea how much light/deep sleep you may be getting.
Pretty easy to set up
Seller shipped out quickly

Cons:
Does not keep accurate count on steps
Does not accurately keep track of sleep cycles
Doesnt stay lit up very long to read results.
Cant keep it lit up to see your steps when using treadmill
The Sedentary is not programmable and goes off every 30 minutes.

Sleep cycle:
On the app when looking at my sleep cycle for the night it shows I had 5 hours of deep sleep and 2.42 hours of light sleep. Of course I am sleeping so I really don't know how much time is spent in deep sleep, but I do know that I wake every night around 2:30-3:30 and I stay awake for several minutes before finally falling back to sleep, providing I didn't need to use the restroom. It takes me sometimes as much as 20-30 minutes to fall asleep, so again, I think this is more a general idea of your sleep cycle. I find it hard to believe this part of the watch would be accurate when the steps are not.

 When using my treadmill, I know when I have it set at a certain speed I walk 106 steps a minute. If just going by the watch I was 260 steps off. I then walked around the house several times, and the pedometer did not even register. After sitting and writing down my results I notice the pedometer had accounted for 24 of the 80+ steps I took. I know it says it does not register the first 10 steps, but mine is not registering many more of the steps. Because the watch is made in China, I would not test the water resistant feature, I think that it will stay dry if you sweat but I wouldnt take it in the shower. Today while writing this, the sedentary timer went off, that is a cool feature, however there isn't a way to set how long you wanted the sedentary time to be. Its preprogrammed at 30 minutes. Which after wearing the watch all day, I found having it going off (vibrating) every 30 minutes annoying as it does not reset once you get up and move about. I am going back to a personal timer I can set for an hour.

Bottom line, if you want this watch to keep track of how many steps you are walking-I have found it NOT to be very accurate. So, my suggestion if you want a watch/pedometer that is quite a bit less than the Ifit, like myself, then this watch will work but use it for a general idea. So what it you end up walking more than 10,000 steps, its all for your health anyhow.

It's probably closer to three and a half stars.  TRENDnet is a pretty good company.  I've purchased some other products from them.  This has a least two software bugs.  One I can cause a crash any time I wish.  The other one occurred but I can't duplicate it since it occurs during the early portion of setup.  I decided to scan the QR code.  I have an iPhone5.  This first part is my fault...I could have sworn I allowed the app to access my camera but I might have accidentally slipped a finger across "NO."  But with the access set to no and one tries to scan a QR code with the app the app crashes.  This means they aren't handling an exception well and that is poor programming.  And this was the second crash I had on setup.  So instead of two minutes setup lasted about ten.  BTW, the setup instructions are a little confusing about passwords.  I used the one on the sticker and it worked fine. Once it's setup I tested the on-off switch on Wi-Fi and cell.  Both worked fine.  So you can manipulate the switch off of your Wi-Fi network.  As for the Wi-Fi extender/bridge, both work fine.  I assume most people want the extender...keep in mind this halves the bandwidth but most people aren't using 50% percent of their routers bandwidth now.  The bridge function is nice if you want to give a guest their own network.  So it has some bugs but you can get through them and the device works well.

I invested in two of these units, they didn't last very long before becoming useless. Before bricking, they worked fine, lasted about a week per set of batteries, captured GPS information reliably. But if longevity of the units is important, then another brand will be better for you. If you're OK with disposable technology that has a limited working life, these are for you.

This was purchased as a gift for my wife, who is a workout fanatic.  After reviewing several devices, this seemed to balance functionality with price.

The good:
It's easy enough to set up, and the band itself is comfortable.  It also does seem to accurately track activity.

The bad:
The monitoring app and software for PC/Mac leaves a lot to be desired.  Syncing can be finicky, and the software runs as a service on the machine (and in the taskbar).

The really bad:
Battery life.  I'd expected 5-7 days of use before recharging, but it's generally half of that.  Add to that the limited memory (if you're not syncing regularly), and it's a fairly high maintenance device.

At the end of the day, I have to believe there are better devices out there.  I've since read that a few of these had less than stellar battery performance, and it's possible that this was one of them.  If the battery issue was resolved, this is easily a four star, without the fix though I'd advise caution.

Let me first say that I researched many of the wrist HR monitors out there and Garmin seemed to offer the best bang for the buck. In terms of functionality, visibility in the sun, swipe menu's etc. I won't go into much detail here about that because all of those functions are great. Also, in terms of the app, the UI is ok. A bit hard to navigate and not as intuitive as Fitbit ( my wife has the fitbit Charge 2). Also, the integration into MyFitnessPal works great. Finally, it's water resistant! The sleep tracking function is also pretty good. Maybe not 100% accurate but good enough to get a general idea of your sleep patterns. Now the reason I'm giving this watch a solid 3 stars:

1. I discovered a major bug in the Garmin Connect app for iPhone a week after I had the watch. It turns out that you cannot turn off or change the alarm time setting to the vivosmart hr+ in the app. Every time you try to either turn it off or change the time it looks like it works and syncs but then you go back into it and it's reverted back. After a few frustrating tries and the annoyance of having to turn off the watch at night (don't want to get up at 5:45am on a Saturday) I went to Garmin support and apparently they are aware of it and are "working on it". No specific timeline available, just "working on it". BUT in the meantime if I want to change my alarm setting I must do it via my computer with the sync cable. HOW ANNOYING.

2. The watch sucks for tracking my weight training HR and interval training sessions. I know for a fact that my HR was at 115-120 at different times and the vivosmart hr+ read at 89. It almost seems like it's taking an average.

2.b I think because it's terrible at tracking accurate HR intervals for weight training / cross training sessions, the App doesn't have that option on their "Activities" menu. You have have to select "Other" to track this and even then it's not totally accurate. It just tracks your time but HR intensity is laughable.

Overall it's a great watch with these pitfalls. If you're more of a runner or biker and want to track your HR rate with GPS and other app integration it's great. If on the other hand you're like me an more of a cross athletic trainer that wants a more accurate HR for interval training, it may be worth looking into other options.
