Had bought for my iPhone 4 in a Bumper me this cell phone holder. The notes and wobble-free-even on the motorway or off the streets. The suction cup is excellent. The rubber material itself already adheres to various surfaces such as rough fittings in the car, desk, wood, glass, etc. One can get rid of dirt and use it again and again with water. To fully securing the Oso Dash Grip vacuum lever is operated and the whole holds bombproof. Absolutely great! The clamp for fixing works like a clothes peg and now holds my Samsung Galaxy S3. This, however, not quite wobble-free, because the phone has a small area on the edge. You can also fine a navigation device or a Garmin GPS can hold. The ball end can rotate the phone in almost all directions. In principle, of course you can pinch anything.
All in all a very good mount for attaching everything fits in on different surfaces.
