I have 2.

I use the one that came with my Garmin package. The out front version that has Garmin printed on it. Works just fine. I also have a K-edge one that has the go pro mount on the bottom. I prefer the k-edge one its made really well and its nice looking. But it was $50+ too!! I have not had an issue with either.

Here is the kedge I have:
