Read reviews; I saw the review video posted and thought the price was good so I bought it. I thought the previous feedback on the instructions might have been an accident. But they are really bad. I've carefully gone through the instructions a couple of times, and strange things are happening. For example, when setting up, it sometimes freezes on the screen and cannot be exited. So I reset it or take out the battery to reset it. Then it freezes and doesn't respond. So far I've been in it for an hour and haven't been able to use it yet. All I'm looking for is my target heart rate and tracking. It seems like a good deal for all the features you get with it, but it's heavy to use which makes it useless. He comes back.
