The watch itself works great and does what it is advertised to do. It does have a real problem with registering stairs. The biggest problem with the watch itself is the band. It is very difficult to get to close and it will unlatch and fall off. So far I have not broken it or lost it. I have how secured an elastic to the band to prevent total loss.
