Apparently not every protective case can provide us a comfortable grip. So if this is what you want, the Tablet Claw should be a nice solution except a protective case with handle.
The Tablet Claw is a multi functional grip solution designed for iPad, Android tablets, and any tablet with a 10.1-inch screen. The grips of Tablet Claw are made of flexible plastic in order to securely hold the tablet in place, while the over-molded urethane rubber can protect the screen. And its flexible construction makes the claw fit most form fitting protective cases. All you need to do is to clip the Tablet Claw on the back of your iPad 2 or other tablet, the integrated ring will offer a secure and comfortable grip. Apart from that, Tablet Claw doubles as a tablet stand that can hold your device in landscape viewing mode or provide you a low angle for typing.
The designers of Tablet Claw are raising fund on Kickstarter at present. Pledge $40 will let you own a Tablet Claw. If you’re interested, jump to Kickstarter for more details.
