The mount is quite small but really clings tightly to the windshield. I work in alaska and with rough road condition it has never shaken loose or jarred. It seems to happen more frequently when it's extra hot/humid out.

It works great 99% of the time, but i sometimes find myself returning to my car to see my dashcam dangling over the dashboard because it lost suction.

It works, sort of. What a piece of junk. Don't waste your money folks this thing is a * scam!

It snaps in but ball is too loose. Falls off constantly which in turn drops the camera onto you hot dash.

Only get this if mounting front camera near the top of window. If mounted upside down to get the correct angle on the stalk, the camera just points at the suction base blocking the entire view.

Garmin keeps popping off. Maybe that's 7 centimeters, it certainly isn't 7 inches. I've had several of those all prove they can't hold any of the bigger gpses that they came with.
