The Polar Loop 2 has a smooth design and a digital display face that all but disappears when not lit, which makes it look less obviously like a fitness tracker and more like a simple bracelet. And as one of the few waterproof fitness trackers in our review (resistant up to 20 meters), there’s no worries about jumping in the lake or river with it on. An 8-day battery life is longer than most rechargeable options, and charges via USB when needed. One annoyance was adjusting the size of the band: you have to remove the clasp and cut sections off the band itself, which is a very permanent sizing choice. But testers found the device comfortable.
Pros: It is a comfortable and sleek tracker that was accurate with some tracking, such as distance and calories burned, but less accurate in some testing situations.
Cons: Activity tracking didn’t seem as accurate as when tracking specific minutes, and sizing the band is a hassle.
Tester Comment: “I like the design and it’s comfortable to wear all day and all night. However, it didn’t track my run accurately. On a 52-minute run, it only logged 27 minutes of activity. It seemed to accurately track distance, though, which is important.”
