Here is my first review after 1 week of use. So far I've fully charged it once when I first opened it and I've been using it 1-2 hours every day for 1 week and the battery stays on. It can be attached directly to the chest, but I use the supplied chest strap. It works as advertised for heart rate monitoring, very simple and straightforward. It's light and the chest strap is comfortable. If there are any changes, I will update the review. But so far so good.
