This is even nicer than I expected! I've had this for a few weeks now and have no problems with its tracking on the metal plate - it's virtually silent. I've kept it at home but you could definitely put this under your desk at work without bothering anyone. It's heavy but not unreasonable at all; I move it a lot. It's not very difficult to balance on if you want to use it standing. And the stats tracker seems to work great.

I recieved this Friday night and began wearing it immediately. I began tracking my calories and activity balance in earnest on Saturday. It's taken some tweaking on my part for sure, having to put forth the extra effort for activity and practicing extra restraint when my coworkers offer me candy treats and girlscout cookies... but I've lost almost 3 lbs already, and its only been 4 days.

I'd used calorie tracking programs before, and had been completely gung ho about them - SparkPeople and Weight Watchers, but somehow they didn't work for me. I think the added incentive of the physical reminder on my arm has really upped my game. It's easy to add foods, easy to track calories. I've found that the app for my android doesn't really like to add your own foods (at least I haven't figured it out yet), but as for tracking things already in the system, it's a breeze.

One thing I'm not too sure about is the sleep monitor - I have really bad sleep apnea due to awesomely large tonsils (which I'm having removed and should alleviate the apnea.) It says that my sleep is 93% efficient - I'm not so sure about this. It does accurately measure when I physically get up to go to the bathroom, or even sit up to fluff the pillows and flop back down. But since it's not tracking my breathing I'm not sure how much this added feature is worth.

Other than that, I really like it. I pre-purchased a year subscription to the monitoring site, so we'll see how that goes. So far I'm still gung ho and really into it :) I have a goal of losing 20 lbs before my tonsillectomy (actually UPPP for those who care to look it up) on July 1 - so we'll see! I'll update again then.

This tracker works well for what it is and for what the price was. It is built well, and I have never had it fall out of the band while wearing it. I think the step tracker is a little off, but that may because I always wear it on my wrist, which may affect the results. Overall it works well, and the app works well with it too. It always syncs and the data is just enough to know how active you have been throughout the day.

This works great so far! It might not be 100% accurate, according to some. But it'll let you know if you have a problem

So far so good, the cats are using it so I guess that a success. It does track a good bit though.

Getting thwm set up is the hardest part. Still working out the kinks, but they work well. Would recommend these to anyone looking for stat tracking system for not a lot of money.

I've owned the Vicoactive for a few months now, and overall it's a great smartwatch and gps tracker.

Cycling: I've used it during long (50 miles+) bike rides, and it matches distance and speed with my bike-mounted detector almost perfectly the entire time. It's much more accurate than apps like Strava or Map my Ride, and as a bonus, it syncs to those apps if you like to use them. Because my ride involves some stop signs/busy intersections I enabled the auto-pause feature, which is a great option since it means the watch stops tracking when you stop moving, which keeps your average speed from plummeting if you get stuck at a long stop light.

Running: The watch performs as expected. It captures distance as speed pretty accurately.

Treadmill: The watch is surprisingly accurate on the treadmill. Over 2 miles it's only off by around .05 miles. It seems to slightly underestimate my running distance, but slightly over estimate my walking distance, so over a few miles it evens out.

Heart-rate monitor: The soft strap heart rate monitor that you can add as an option is surprisingly comfortable. It's really useful if you want to track how hard you're working out.

Other features: Survives the shower with no issue, is overall comfortable. I also like the interchangeable straps, and the different watch faces, since it lets you make the watch a bit more feminine. The white color isn't as nice as I would have hoped--I'd recommend the black option. The white looks a little like a kids watch. Overall pretty durable. I've knocked my wrist and arm on things and there's been no serious damage. Step counter seems accurate too. The alarm clock is great--it allows you to set multiple alarm clocks for different days, so you don't need to keep resetting the alarm. The vibration is enough to wake me up without annoying me.

Critiques:
1. You can't see the time when the watch is in GPS tracking mode. This is a little ridiculous. It provides you with numerous data screens, and yet the time of day isn't on one of them! If this wasn't an issue, I'd give it 5 stars.

2. A little clunky for reading emails/texts. It works, but it's not easy.

3. Not alot of back-light. In daytime conditions its fine, but if you're running or walking in the evening or in low light conditions, its hard to see the watch face without pressing the light button.

4. Scratches easy. You need to get a watch face cover. Within a month I had tiny scratches on the watch face, so I got an armor suite cover for it before I got any truly noticeable scratches. No scratches are noticeable unless you really look hard at the right angle, but it's covered now so I'm happy.

I got this on March 2nd and I have used it constantly since. I will admit the tracking food on the website can be a bit of a pain, especially when you cannot find the food in the database. Home made meals are a guessing game. But for most items it is just the time it takes to select it and knowing how much you ate. The goals are easy to set and seeing how well I do towards them makes me feel accomplished. Being a gamer, I like the little reward badges you can earn. I have already earned 5. So far it is a great tool to keep me on track. It was also interesting to see just how much sleep I actually get. It was not as much as I expected but it is accounting for how long it takes you to get to sleep and if you wake up, not just when you lay down and get up. I am over all very satisfied with this. I was iffy because of the price and there was a lot of looking at the pros and cons from reviews. I read that some people had trouble setting it up but for me it was plug in the charger, let the program and driver install, set up your account and I was off with it. Just do not bounce around in your chair too much or the pedometer function will count them as steps. I have not had to contact customer support so I cannot say if it is any good or not. Most of the low reviews I had read were on the customer service. On my experience with the Fitbit so far, I would recommend the device to my friends and family.

Works great; easy set-up and seems to be dead on accurate.

I like how easy it is to wear, how it tracks my primary activity (walking), and how easily it syncs with my computer and displays my results daily and over time.

I only used it a couple of items, but I am really satisfied as I can accurately keep track of the distance, current speed / pace and heart rate if desired. I recommend it.

I have found this to be a really good tracker and pretty accurate. It works well in syncing with other apps. The only reason for 4 stars is that sometimed it tracks some activities poorly. Stair climbing is a real problem. For the important measurements like steps, sleep and heart rate it works great.  The app sets challenges for me and that seems to help me in terms of moving around more than I did before getting the tracker.  I would definitely recommend this for all exercise levels.

This is one of the latest among many different brands of wearable fitness tracking devices.

Its designed to monitor how much activity you get and how much rest you get, each day, and track it over time so as to keep you on track. It is very good at motivating you to keep activity goals.

Whats distinctive about this one is the focus on recovery: making sure that you get enough rest so that you are ready for the next exercise. It does this by measuring heart rate variability (it doesnt report your moment to moment heart rate, though) and also your activity and sleep patterns.

To track activity, you need to download the app, and it works on both iPhones and Android phones. The app connects to the device via bluetooth. It does automatically recognize what kind of activity you are engaged in, whether you're walking or running or cycling or swimming, for example. When it is working it shows a helpful timeline of what you are doing throughout the day. I really found it eye-opening, for example, when I checked on the second day and noticed that Id been sitting down for about three hours. It motivated me to try and get up and move around every hour or so.

There are three bands that you can fit the device into (and each one comes in a larger and smaller size): one is a harder rubber, that kind of looks and feels like a watch, except it clips together via magnets; then there is a sports band and an ankle band, both are rubber/silicone and pull over the wrist or the ankle. You charge up the device via a USB cord and a little magnetic charger that clips onto the device, and then it is supposed to work several days without needing to be recharged.

Also, I found that it seemed to monitor sleep accurately the first couple evenings, but then it said Id slept only a few hours when Id gotten a full nights sleep. When you take it off, also, it seems to register that you are sleeping.

Still, even when it is accurate, I guess Im having a hard time seeing why this would be helpful. I think that if I wasn't very active, this might serve as a reminder to get active. Or, perhaps, if I never got a good nights sleep, this might remind me to do that. In fact, I usually get a pretty good nights sleep, and I get a moderate workout in about six days a week. When it wasn't tracking my sleep accurately, it suggested I needed more rest before a workout, but because I am pretty regularly active, I have a pretty good sense already of how much sleep I need.

It also doesnt seem to be very accurate in measuring activity levels. As with the sleep monitor it seemed to work well at first, and I was able to meet the activity goals easily. Then it seemed like no matter how activity I got, it didn't ever meet the requirement. It just didn't seem to be registering how much I was doing.

I think that if the performance bugs were worked out, this might be pretty useful for someone who is wanting to begin a new healthier lifestyle. Personally, I haven't found it very useful. Combine that with somewhat erratic performance and this has basically gone into my drawer and not getting use.

It works perfect for me. I love the habit tracker.

Fitness trackers are huge now as we begin to be more aware of our trend toward inactivity as a country. Unfortunity, not everyone can afford to pay the premium for name brands, and that is where these types of devices come in.

Learning how to operate this tracker will take a little getting used to, but it's nothing you can't figure out without a little tinkering. The step count is a little bit higher than it should be, at least when compared to the tracking on s health and my gear s2, but this doesn't matter too much. It's a measure of activity either way.

The color is a nice purple and the feel of the silicone band is soft. It went on easily even on my 7 inch wrist. It is also very comfortable and did not feel bulky while wearing. The screen is very simple so the battery lasts a long time between charges, which you do by popping the black part out of the band and sticking in a USB port.

The main issue I have with this is the app. It controlled the device just fine, but I did not like that it hangs out in your notification bar, or that it is a bit of a battery drain. There was also no easy way of closing it as far as I could find. Had to go to task manager.

I received this product on promotion in exchange for my honest and unbiased review. I think the app needs work, but it's nothing that firmware updates can't fix.

So far this thermometer is working really well.

So far it has been working very well. The gps tracking on runs is probably my favorite aspect of it thus far, and I have found its heart rate tracking to be for the most part reliable and a good measure of actual heart rate, if sometimes it lags a tad behind. (I test it every now and again against my pulse, even during runs.) The sleep tracking has also worked quite well, and I was surprised to see how accurate it is with respect to determining when I go to sleep.

Only warning is that it takes a little while to get used to its fit. It is slightly more snug than a standard watch - at least how I wear them - since it can't be sliding around, and for this took a bit of adjustment to find the right fit that keeps it in place and is comfortable.
