Standing, light housework


Walking and other medium intensity activities

Intensity levels

Loop 2 is rated 3.5 out of 5 by 47.
Rated 5 out of 5 by from Works Great! I purchased the Loop 2 because it's waterproof, large display, and comfortable to wear and sleep in. I also wear it for my water aerobic class and it still tracks my steps. I like it so much I bought one for my husband and 8 year son. They like it more than I do. It's also easy to set up.

Rated 4 out of 5 by from Great tracker/ horrible clasp I have owned the loop 2 for about 2 week. It has all the features and is comfortable to wear. But!!!! The clasp is horrible. It pops open all the time. Not what you want with an activity tracker. I really think polar should offer a replacement clasp for the loop2. I would give five stars if the clasp worked.

Rated 5 out of 5 by from Great product Love this device. I bought my Polar 3 years ago. I almost replaced it with a Samsung but loved this design more. Like many others I thought this monitored my heart rate but learned I didnt miss the featute as time progressed. I want a new monitor and it will be by Polar. Good features, waterproof, clasp design is perfect, and lightweight

Rated 4 out of 5 by from Wish it had better features! I bought this for the new year trying to make 2017 my most active year yet! I love the product look and that is mostly why I chose this item. The Polar Loop 2 is much sleeker than other available choices and even the ones that are more sleek than this one do not have the features that this one does. The features are nice, but I do wish they were more advanced. Tracks my sleep, but does not tell me how I can improve my sleep. Gives a SUPER nice alarm that vibrates to wake me up, and I have never had such a gentle daily awaken in my life. However, you can only set the alarm as on or off, only gives the option to set one alarm, and you can only choose from everyday or mon-fri. The product also lets you choose from low activity, medium or high activity levels. This way it can tell you how close you are to meeting your goal. However, the goal is not YOUR goal. It is a goal set by the device that it thinks you should be reaching. Every person is different and everyone has different goals to meet. I wish that this product had BETTER features, but for the features it does provide, the price I paid, and the amazing PINK color.....there was no better choice than this product. I would highly recommend this product, especially for lower activity people or people that are not demanding with extensively advanced features. I also love that it is water proof (not resistant) and that it connects to my phone. Be aware that the wrist band must be permanently cut to size by yourself when you get it, and the size guide they give you seems to be off a bit. I cut mine to the size I thought I needed based on the paper guide. I thought maybe I would have to adjust by one more section. I actually had to cut off much more than that and its still a good bit amount of loose on my wrist when the paper was not. However, either way - I figured it out and it does fit nicely and you cant even tell that I was the one that personally sized it. I love that it is a watch as well as I have found myself never wearing my normal watch any more these days but ALWAYS wearing this tracker. Another note: my skin is SUPER sensitive to metal and other stuff and this has NEVER caused even the slightest irritation to my skin even thou the band has a metal piece that is always touching my skin. I know that this company has more recent and advanced options for trackers available but the look of the tracker was a main thing for me. Hopefully even thou this item is not their newest, there will be updates that give more advanced features.

Rated 1 out of 5 by from Awful There was no heart monitor on the Polar and it was too hard to put on and too hard to read, we bought a Fitbit

Rated 5 out of 5 by from This one swims! I bought this white Polar Loop to replace my previous black Loop. I swim and have confidence that it will safely track my activity in the water. If you swim, this is the only activity tracker for you!

Rated 4 out of 5 by from Great device Very comfortable and reliable. Sturdy, can take a lot of abuse from workouts and daily living. The app is almost perfect. The battery life is about 4-5 days with two hours of HR monitoring and no notifications. I wish the visibility was better when the sun is really shining. I had the first version, this one, and am looking forward to have the third.

Rated 2 out of 5 by from Display not working I bought the Polar Loop 2 and HR7 through amazon last week and loved them. I've been more motivated to go to the gym and get all 10k steps in. However, one week into owning the Polar Loop 2, I've had a few issues. My display is no longer working once my battery drops below 70%! How annoying is that! I was really hoping I could use this for my Corporate health challenge that starts today, but it looks as though I'll be using an old school pedometer since I can't always guarantee my polar loop 2 will have a battery level > 70%.
