Good bell to run, pretty elegant made to fit everyday too. Good feedback on training sessions and rest period. You can also enter your own app that shows map coordinates, so you do not need a full-featured clock.
The running function does not work well for styling.
Has broken the screen once, therefore it gets a little move. And you depend on the pressure sensitive screen, not everything can be done with the buttons. Newer and older variants have buttons, which I think are an advantage.
