Bought for Samsung gear 2. Fits perfect. Heart rate function still works. Buckle is a little odd with the extra loop at the top...it doesnt do anything but looks like it will snag on things. Havent worn much yet so i don't know

Perfect fit.  I am 86 old Masters track and field athlete. Time of year get ready for season. I have maintained. a 34" waist for prior 21 years until last year. Inactive due prostate cancer radiation treatments. Needed this additional compression to get back to normal size. It did the trick.

ORIGINAL REVIEW:
_____________________________________________________
Thoughts:
First off, all that i was looking for in a heart monitor was the ability to see my heart rate, see if i'm in the zone, and see how many calories i have burned. This watch does all of those functions flawlessly! My family has a history of heart related problems so when i workout, i need to make sure that i am not putting too much stress on my heart while still maintaining a high level of work. I use this primarily during cardio routines of P90X but i will use this more for running once it gets warm outside.

Functionality/Use:
The watch is incredibly easy to use. When you first open the box, you go through a setup wizard on the watch asking you to input information such a weight, gender, and units preferences to better tailor the results to the individual. After that, you are literally all set to workout. While many people have had trouble getting the watch to pick up the signal from the strap, i have found that licking or wetting the strap works wonders!
Something else that i would like to point out is that the watch have the ability to **beep** when you're out of your zone (either not working hard enough or working way harder than you should be) that is priceless! I have found sometimes during my workouts that i'm pushing myself really hard and i end up getting my heart rate above 185 BPM which is not really the best thing to do. This **beep** is great for some workouts but terrible for others. Luckily, you can turn the **beep** off very easily. I prefer to turn the beep off if i'm going to do interval training like sprints or something where my BPM is not always in the zone.

Other:
Just a few quick things i would like to point out. I've read online that detaching the heart rate pod from the strap will make the battery last longer. I am not sure this actually does anything, but it gives me ease of mind thinking that i am actually making it last longer.

Pros:
Lightweight
Comfortable
Easy to use
**Beep** while outside of the "zone" is a great feature that can be turned on/off
Cons:
None

Overall:
Overall, i can't think of a better watch to spend my money on. No, this doesn't give graphs on how you're doing over time but that is not what I was looking for. This is a great buy and i have used it for a good period of time and have had no issues at all with it.

UPDATE AFTER 2 MONTHS
_____________________________________________________

After two months, this watch is still working perfectly! I have had no issues and i love that i have the ability to look at combined totals of my workouts! As of today, i have burned over 35,000 calories!!! This feature is something that keeps you motivated to keep working hard.  Before this watch, i never was that into working out.  Now when i run, instead of going a certain distance, i like to aim for a caloric goal (about 1,000) before i end my workout.

I still highly recommend this watch to anyone looking for a great heart monitor!

Fits perfect. Just had my old core support cut off and had a body alignment done and this part fits perfect.

*** Update 5/2/13*** It is a pleasure to report that it has been almost 4.5 years and this product is still working flawlessly. I used it on a 5.5 mile run and it is as good as the day I got it. See comments to this review -- others have made good tips that I agree with. The bottom line -- if you are still using it after this amount of time, you are either ready for an upgrade or at least won't mind having to buy another unit!

Original Review:

I'd hoped that getting this new running gadget would encourage me to exercise more often. So far so good. I asked for this for Christmas and, well, it has accomplished it's primary function for me... I've been running almost every day since I got it.  I was turned off by the gigantic size of some HRMs, and did not need something to keep track of splits as I run on my treadmill at home and the gym.

As a heart rate monitor, the functionality is pleasantly simple. It tracks your heart rate for the whole workout. You hit the big button to start, and it goes to work tracking the length of time, the average heartbeat, and the peak. While you are running, it displays your current heartbeat. That's it -- but sometimes it's better to keep it simple.

I should point out that, as a watch, the watch piece tells the time and date only. If you want/need splits and a stopwatch, you should look elsewhere.

Here's some other thoughts: I was worried that the strap would break but realized after a couple workouts that I was probably wearing it a little too tight. Since adjusting, it is much more comfortable, has not fallen off, and, as a guy, you *almost* forget that you have it on. My wife cracked up when I took my shirt off after a recent workout. She said that, from the back, it looked like I was wearing a bra (or Manzierre, or Bro, if you prefer).

I had no original intention of wearing it while NOT working out, but I've found it addictive, and have enjoyed observing how drinking a cup of coffee while sitting at my desk does raise my heart rate about 10-15 beats per minute on average. Also, as I've started to get in a little better shape over the last 3 weeks, I see that I have to run either farther or faster to get my heart rate up to certain thresholds. And, now my heart rate does not go up as high from merely climing the stairs at home. I believe that these insights, among others, are very encouraging for someone who is just getting back in shape. The encouragement aspect combined with the simplicity makes this a great starter heart rate monitor for anyone considering.

This sport armband works well for running.  I use my naked Galaxy S4 with the wireless charging cover in this armband.  The wireless charging cover makes the GS4 a bit thicker and it fits fine.  I've also test fitted a GS4 with the&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Otterbox-Defender-case/dp/B00C96CGXW/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Otterbox Defender case</a>.  It doesn't fit with the full case, however if will fit with some effort if you take the outside rubber casing off the Defender case and leave the hard plastic on the phone.

The Android 4.3 release for the GS4 enabled ANT+ wireless functionality.  I'm waiting for the Garmin 910XT replacement so in the meantime I like using this armband and apps to connect to my&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/ANT-heart-rate-strap-monitor/dp/B00BI9X1QM/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">ANT+ heart rate strap monitor</a>&nbsp;and&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/ANT-footpod/dp/B00264GKVQ/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">ANT+ footpod</a>.  It's a great combo that can alleviate the purchase of expensive GPS watches.

I don't run in the rain with this armband.  There is a large top slot to slip your phone into and rain can just pour into it.  When running on some warm days with the armband against my skin, there was a good amount of moisture inside the neoprene jacket and on the inside of the plastic window.  I was a little concerned that this might cause an issue over time.

I don't use that silly earphone cable tab on the left side.  It's a bit misplaced coming out the side- on the GS4 your earphones would come out the top.

When running in cold weather I use a wind jacket and this armband does not stay in place well on my upper arm.  It slips down to my elbow, so I either need to cinch the strap very tight or keep my elbow bent  so it doesn't fully slip off my arm.  The armband should probably be redesigned to use some rubber grips on the inside to keep this from happening.  Or else there should be a different model to chose from that has this feature in case you wear slippery athletic clothes.

When pressing on-screen buttons I often have to press them many times.  The plastic window gets in the way.  I don't use a screen protector on the phone.  The power and volume buttons are difficult to depress on purpose, yet they unexpectedly get depressed on accident.  I only start/stop my exercise so I don't look at it much.

This armband works for my purposes and I'll continue to use it.  it's not perfect, but it was inexpensive so I'm OK with it for the time being and not looking for an alternative.

As a triathlete back in training (a few years off due to achilles, plantar fascae and heart surgery). Have only had it for 1 day so will give another review update later. But at this point- picked up HR right away and correct HR at that. Some have mentioned numbers that were way off- keep in mind there is a mode function that asks you if you want to diplay HR as beats per minute or as percentage. If this is in the BPM function then your HR is accurate.  I do like the review/recall function where I can go back and review my split times as well as my Avg HR during those split times as well as MAX HR.  I enjoy the function of manually setting my HR zone- you enter the zone 1 range, Max HR and it then gives you zone 2-5 range. For that point alone- I am giving it a 4, I haven't tinkered with the rest of it and it's other functions- once that is done, I'm sure I can give it a 5.

Update:*****Had this product for almost a month now- other then getting used to it, or pushing the split button instead of start/stop button- It has done everything I've expected it to.  I've recalled all split times, avg HR times, max and min HR time as well as time in zone training.  Calories burned- really don't count calories burned, I just watch my weight and either increase my workout load or decrease my intake.
Overall- 5-stars, no issues with what I've asked of it. I can move in and out of the HR training zone when brick training and transitioning. Can also capture my own transition time during brick training with split function.
This has been a great product up to this point.

I received this yesterday , 5 days earlier than expected. and so far am very happy with it. The band is sturdy and lightweight. My fitbit Zip fit in snuggly. The band fasteneds with a small metal-like button that is pushed through one of the holding holes. It seems to stay tight so far. The rest of the band fits perfectly through and behind the band so it doesnt snag on clothing. Actually at first I found that tuck away method a little confusing, but after wearing it a day, was grateful it kept out of the way.
My wrists are extremely small by anyone standards and truly thought I would have to create another holding for the "button" but tomy surprise it fit.
All in all I am very happy with it. If you are worried about forgetting about your Fitbit Zip being clipped to clothing and it ending up into the wash like I was, this is the perfect solution. Just remember to remove before showering and youve got it made.
I gave it 4 stars instead of 5 because the decorative part leaves something to be desired since FitBit is something people are going to use and wear 24/7, should have a little more thought put into it. Functionwise though, its perfect.

Fits perfect. It's heavier than others I've tried but it works. Would have liked patches for 'Emotional Support' instead of ones saying 'Service Dog.'

I bought this to monitor my heart rate and track my calories.  I have had it about a month and it does its job.  I use it at least 5-6 days a week while I work out.  So far it has worked like a champ and syncs with the treadmill and elliptical bike.  I would like to be able to sync it up with my laptop but take the data logs myself and track them in a spreadsheet so not to much of a bother.  Works great.

Fit is perfect. No worries about dropping my Moto Turbo 2.

I got this as a replacement for our Life Fitness F1 Treadmill. The heart rate monitor works great, it automatically paired with the treadmill. And it's worth it, working out with the automatic cardio program is much better.

This sports bra is fantastic if you also wear a heart rate monitor strap for exercise. The band around the bottom is long (lengthwise) but thin (fabric thickness-wise). I've had problems with bras that have a thick elastic strap around the problem. It's also generally very comfortable. I ended up buying a second one in a different color after this purchase.

Fits and functions as it should. Option for colors would be great

Got this v-belt to replace a worn belt on my treadmill.  It fit perfectly and so far is working perfectly.

Gear Fit works great but the heart rate monitor did not like due to you have to be still to take reading, if moving does not work.  I have slow heart rate and use it  a lot.  Other than that its okay.

***UPDATE***
6/8/14- I've now had this watch for nearly a year (about 11.5mos). I have lost more then 20lbs since I got this watch and am still using it on a semi daily basis for walks and keeping an eye on my heart rate while exercising. It is basically the watch I have on when exercising or doing anything casual (since it is obviously not a dress up or 'nice looking' watch). It is still working exactly how it worked when I got it. The heart rate on this watch matches the heart rate on my stationary bike within a beat or two (might say 122 or 118 instead of 120 or etc... but also might say 120). I really have no complaints about this watch or the durability. Certainly not the durability over time. It's gotten pretty regular use for very nearly a year now and is still working as it did when it was new. For $28 I really can't complain about that at all.

7/9/13- This watch is wonderful for heart rate tracking. The calories are significantly lower then what exercise machines say. Still, I am happy with it . It also works well as a pedometer and distance tracker during walks/jogs. I figure out of the five functions I bought it for (being a wrist watch, heart rate at a touch, pedometer, distance, calories) it does well on all but one. So four out of five stars for four out of five objectives met. As far as reviewing worth- I bought mine on sale for $28. Overall, for the $25-$35 price range I would say this is well worth it. If buying again I would not spend more then $35 on it.
