Loop 2 is rated 2.6667 out of 5 by 9.
Rated 4 out of 5 by from Love it! I've only had this for a couple weeks, but love it so far. I loved the fact that I got to size it myself. I wear it loose, more like a bracelet. I really dislike watches. The sizing took about 10 minutes because I only cut a little at a time and then put the clasp back on after each snip to try it on to check it. I was scared I would cut too much & it would end up too small, so I was very careful. I did well. It's perfect. I had a Fitbit charge hr a while back, but returned it because I didn't like the material and the fact that it was so watch-like. I like the style of the loop 2 much better. Sometimes I have to push the button 2-3 times in the loop 2 before it syncs with polar flow, but I tend to charge it while I'm relaxing after dinner, so it syncs then automatically. I wish they had put the optic heart rate monitor in it, but I'm sure they will eventually. I also dislike wearing the heart rate straps, so having it reading from my wrist would be perfect for me. All in all, I'm happy with it. If they make a loop 3 with built-in heart rate, I'll be thrilled...preferably kelly green. :-)

Rated 3 out of 5 by from Love what it does, but I can't keep the clasp done I love that this pairs with the heart rate monitor chest strap, and I love the tracking app. I love Polar products, and I find them very useful in tracking my fitness and calorie burn. This product is a great concept, but I cannot keep the clasp buckled. I have trimmed the excess band more, but it never seems to get a good connection. If I do much or anything touches it, it opens up. This is a bit frustrating to me. I would be happier if it had a basic watchband closure, or if someone would tell me the secret of keeping it fastened! Otherwise, a great product!

Rated 3 out of 5 by from Syncing problem I love what the loop 2 does. Tracking is fairly accurate and the notifications works great. However, I have problems with timely syncing to the app. Sometimes days go by before the steps are updated even though the app says the device has sync'd. The app even say what time it synced but doesn't log the data.

Rated 2 out of 5 by from The Buckle Has Really Turned Me Off I purchased this product based on a couple of recommendations from friends. Both braced me for start up..mainly the sizing of the band. This task is ridiculously difficult and has no real purpose, as the fit of the band is no different than if the standard watch band had been used. Sizing this band wasted an hour of my time, and when I took it back to Best Buy and demanded to get someone there to size it, it took almost two hours with two different people. I haven't even started using the technology, yet I am extremely annoyed by the hassle of just getting it on. Right now, I couldn't with a good conscience recommend this product to anyone. Hopefully my feeling will change once I start seeing the technology. I have owned several Polar HR monitors in the past and all products have been top notch. I'm really hoping that the technology will be up to standard and change my mind about this purchase

Rated 2 out of 5 by from Needs improvement A little bulky because of buckle style. Buckle also sometimes comes loose. Display is hard to read in daylight. For example, I can't see my HR while riding my bike.

Rated 4 out of 5 by from I like it! I bought this in August and wear it every day. It lets me know how many steps I've taken, as well as when to get up and move. It can also be used as a calorie counter. The synchronizing polar flow online program has many features to track fitness achievements. I wear it loose on my wrist, so no buckle problems. Overall, a great surprise!

Rated 2 out of 5 by from Issue with comfort The metal clasp is not comfortable, not for me. The Nike style band is the way to go
