Loop 2 is rated 3.3611 out of 5 by 36.
Rated 5 out of 5 by from Love it I've had mine for about a year or so and I love it! It's a really great product. I love the waterproof feature (all other are only water resistant) I do wish it had the heart monitor in it (I do have the heart strap). The new one with the monitor came out a few moths later..just don't want to spend the extra money...

Rated 4 out of 5 by from To Sync or Not to Sync The Sync is irritating, seems random. Needs to be more specific.

Rated 4 out of 5 by from Love mine. I have had mine for a year and a half and wear it every day. I have a few complaints but for the most part it does exactly what I want it to do. I love it. I recommend getting the heart monitor to go with it.

Rated 2 out of 5 by from I expected better I have been using the polar HR monitor for years and loved it. When I thought I'd like to wear a fitness tracker I looked to polar thinking theirs would be one of the best. But it's not what I had hoped: battery needs to be charged often; wristband is a bit bulky; hard to read while active; wristband does not switch between HR and time by raising wrist near chest strap while active. Also the chest strap has a poor loop closure - it unhooks VERY easily. Unfortunately I don't use that often. I went back to using my watch/HR monitor.

Rated 5 out of 5 by from Accurate steps, and active and sleep time. I bought my Polar Loop 2 several months ago after having very good results with the original Polar Loop (I gave the Polar Loop to my son and he loves it). I have a Polar H7 monitor that I use with the Polar Loop 2 when I perform HIIT using body weight or cycling (stationary or on the trail). Amazing analysis is available with Polar Flow and the package is very easy to use! I also like the alerts for getting up and receiving messages, as well as sleep monitoring. This is my all around fitness tracking solution and it works!

Rated 3 out of 5 by from Couple things that I would change I purchased the loop II about a month ago. I like the comfort, but would change a couple of things. 1. Can't see it in the sunlight. 2. The clasp is a little flimsy. More to come...

Rated 4 out of 5 by from polar loop 2 i like everything about it except have not found out how to change the time out of military time!

Rated 4 out of 5 by from Good product After returning the first loop2 because it stopped recording, the second one seems to be working well. I have to charge the unit every 4 days, that is more than expected. An improvement I would like to see would be a proximity sensor that would display HR when the chest strap is worn and the band touches or comes close to the strap.
