This tracker was pretty good until it disappeared off my wrist.

Do not purchaseI'll admit they have the best tracker for swimmers but that being said this a waste of money unless you are super crafty at opening the backing

Overall, its actually a really good fitness tracker.

I actually liked the tracker initially.

The tracker falls out of the wrist band way too easily.

This is a great exercise tracker and swimming lap counter.

If you are looking for a very good basic activity tracker, and you aren't a competitive athlete, I would highly recommend the Shine 2.

This tracker is not compatible with iPhone 7/7plus

Very bad R&D on the strap that hold the device.
