You set your smartphone or small tablet in the middle of this device, which holds it in place with a special “micro suction” system and sets up a Bluetooth connection. You hold TREWGrip in both hands and you type, as shown, on a QWERTY keyboard that’s actually on the underside: it’s been split and turned. But the vendor says that if you know how to type, then practice and muscle memory will make you almost as fast as your regular keyboard. A battery gives about 10 hours of typing. You can see it in action in this video. It’s supposed to ship later this year, priced at about $250.
