Last friday my bike handlebar mount arrived from ebay, it clamped onto the handlebars with ease, the controller snaps into it with a firm click and feels solid, my phone mounts onto the controller no problem too. To make it even more secure i had these thick rubber bands lying around, one stretched over the mount and controller and the other 2 over the controller and phone, the setup feels very secure indeed. Going a quite a speed on my local off road trails it didn't budge an inch
