    I have to say I am surprised at how accurate this watch is . It was easy to set up and easy to use . I am not a tech person so I was a bit afraid of not being able to get it to work . I like that I can set the parameters and the watch will do all the work . It keeps track of my steps and notifies me if I need to move more ! The one thing I can say is if you buy this for a smaller person it might be to big for them but an average or larger person it should fit great . So all in all it is a good product and the price was right .
