This is a great tablet arm for owners of a seven to ten inch tablet or other device. It has a huge range of motion and is adjustable. The arm easily mounts with two screws and is secure. Despite other reviews saying otherwise, this arm will fit transformer series tablets, and other 10 inch android tablets. The fit is very tight, but if you place the tablet in one corner and the bottom arm, then slide the other corner down over the tablet's corner, the device will fit very tightly but securely. This product is fantastic for anybody hoping to use their device in a more comfortable. hands free position.
