A great value, very well designed and built phone mount for motorcycle or bicycle. Used with my Fairphone in it's bumper case. I occasionally forget to lock the arms in place, but no matter, the phone is always safe and secure. Fitted for 3 years now (garaged) and has served me well. It is reasonably easily moved between bikes, although there is a need to align carefully on handlebars. With this in mind I decided to buy another for a second bike. Both motorcycles have handlebar USB sockets, therefore I can easily charge with a short lead. I actually bought the slightly more expensive newer model, which has another level of shock absorbency, although I would have been perfectly happy with the original model.
