Bests & Worsts Reviews from Amazon

Consider yourself lucky if the bluetooth works. This is the worst bluetooth operated health device I have ever owned, and not to mention the app that is buggy which continuously tells me my device is connected to some other app. Returning it back and wouldn't recommend this to anyone or any other polar product. How can a company even put a product like this on the market without adequate testing? unbelievable! I wish i could give it negative stars.
