I've tried many of these watches over the years and almost all of the problems have been related to the software they use to control the device and you need a software application to use them use it. I think it's a physically well-built watch, but the software application failed to stay connected properly and was poorly organized. At first I thought this watch didn't have a blood pressure function until I dug into the software and found it. THAT should have been one of the main features on the front page. I would buy this watch again with the appropriate software application written and/or reviewed by an English speaking person. It wasn't that bad, but they don't understand how we use a certain language.
