This thing is super study and doesn't bounce when mounted to the dash. It sticks really well so I would reccomend lining it up before setting it up. It is worth mentioning that I have a solid plastic dash and it did not want to come off the protective pad for the first month I had it installed so I just left it attached to my dash.
I bought this for road trips, any time i need directions. More specifically when i go to the keys from KY this fall.
No joke. The attachment material for this mount is the stickiest I have ever seen, and unless it simply degrades over time, it will not fall off. In fact, just using the windshield mount, I can't simply pull it off!
