Computer mount (for Cannondale SystemBar R-One)

It does the job .. just

The surface is unrefined and rough in complete contrast to a quality bike. The Garmin is easily twisted out of the mount when operating the buttons as it just doesn't click in very well. I found an old adapter which was $5 that I could fit onto the legit Cannondale mount to get a Garmin and GoPro fitting. I am now running that solution as it looks better, does what I need and I am not worried about losing my Garmin mid race. The cost and quality of this mount are very disappointing.
