Very heavily made, suitable for a motorcycle and high speeds. Even violent shaking on rough paths I found the mount solid, and my phone has not slipped, I use an S28 in a protective cover.
For my installation, I used the thinner one of the supplied spacers and put it to the right of the throttle on the very inside over the grip. The Grip is still comfortable and there's no interference with the brake.
The central area of the handlebars close to the display either side on the VX4 have plastic cover's protecting the wires that run in a groove on the handlebars. This was my preferred mounting location, but just snugging it up and testing the motion my phone was seeing floor, ceiling, floor, ceiling. On the trail that much violently moving phone is likely to break something eventually. The bikes display also moved as much as the phone rotating this back and forth so I advise against this mounting area.
The phone mount will also mount between the turn signals and the grip if you roll the grip end over itself a little and use the spacer over one of the adhesive rubber strips included to protect the wire in the groove, Mine is next to the throttle because I used that area to mount mirrors.
