Does anyone know, if there are any handles, or how should I name them, for the iPad, to fit better in my hands? If I'm playing the game for more then just a few minutes, my hands will get sweaty and my iPad Air will become slippy. I tried handshoes, and it is a little better, but a really good handle like something like a real wheel grip on ether side of the iPad, would be really nice. Does anyone know what I mean? Is there something out there for me, that escaped me till now?
