A "Support" worthy of the name. It is stable, does not vibrate when crossing bumps and holes in the road. Nothing to do with the "simple" suction mount comes with my GO 930T, which met at the first bump or hole, breaks the figure with the browser will break it. However the lever firmly fixed bracket on the windshield is a bit difficult to operate. But once firmly attached to the windshield by, nothing moves. Very reassuring to forget that his GPS bracket could break the figure. . . with the browser! Very careful when various requests of the patella, even jaws loosened thoroughly. This is the only point that put me **** 4 instead of 5. Sorry!
