### ⭐ "The biggest piece of dog ____"
*by D***M on November 2, 2022*

This heart rate monitor is some absolute garbage. First, the app itself is trash, hard to use, and there is NO WAY TO RECORD YOUR DATA. It only shows you your heart rate live, so you can't actually look back at it. If the product developers had common sense or at least functioning brains they would realize that if someone is using a chest strap heart rate monitor, they would want to use it for exercising. And if you're exercising, it's difficult to record your levels of exertion while you're exercising, which is why most people want to record their data. Even if you connect it to an app like Apple health, the minotir is liable to spontaneously disconnect for no reason at all without notifying you. You can't turn it on and off, and if you connect it to the app, YOU CAN'T CONNECT IT WITH ANYTHING ELSE, so the app is a waste of storage. As a mechanical engineering student, I honestly believe I could build a more reliable monitor, given a day and some materials. This thing is worse than an absolute disappointment, don't bother with it And the customer service didn't help at all.
