Very good. I have had mine for 18 months now and have not experienced any problems with it.
Being able to download your runs and keep track of how you are progressing I find useful. Several setting you can use for differnt types of training are good.
Feels a little big to wear initally but you get used to it and can take a while to find a GPD connection sometimes
Very good. Easy to function and use.
