The bracket on the handlebar is bit shaky, although adhesive pad plus rubber is used. Really slipping does nothing, but it has some play.
Operation is with 4 keys take some getting used. In particular, during the journey, you can retrieve with the right top and bottom button various indicators, which is a bit awkward, especially since one just has to get used to it, what ads are on which key.
So overall a good bike computer, which is certainly worth the price.
