ambivalent impression, but total of positive.

After ordering the supply was there very quickly. The packaging has somewhat surprised me, as I held up two plastic bags in hands after opening a maxi letter. Was clear from the labeling that the product offered here actually includes two products, namely once the mount for the handlebar and secondly an adapter plate for the Garmin device.
The clamp for attaching to the handlebar works well thanks to the enclosed rubber piece and keeps very safe. The quality is also good. But I would have wished that the nuts are glued or clamped in the plastic, so that they can not simply fall out during assembly / disassembly.
The adapter plate snapped at me at first, although one, was too easy to remove. With a little reworking, it snaps now a clean and tight. But you should make sure in any case, the holder right to assemble around, so the nose down. This is clearly seen in the assembly instructions also.
My Dakota snaps in the disk clean and tight. In your first few rides on road / cobblestone and unpaved dirt roads wiggled or broke anything. Obs also downhill and mountain biking holds I can say nothing for lack of experience.
Total of the product convinced me (certainly better than the original accessories). Deductions there for loose nuts and the beginning not perfect fit between adapter and bracket.
