Just got this phone mount and holder in today. This is a very solid mount that has zero vibration when driving. I had first purchased a Scosche universal mount and holder at Wal-Mart, but due to the long nature of the mounts flexible and bendable arm, my phone vibrated like crazy. I got a video here sampling a movie and Slingplayer on my Droid Incredible. Of course, I'm just sitting in the garage. I can post up another video of driving down the road if anyone likes.
