If you game on your tablet or if you like controlling devices with your phone such as drones or RC cars then you might want to give this a look.
The ScreenStick is a very straightforward and easy to use device. Simply stick the Suction cups to your device and begin playing. It's purpose is to prevent your fingers from slipping and allow for more precise control.
There are two different types of sticks that are available for use, the simulator stick, and the gaming stick. The simulator stick is modeled after an RC stick and is more for simulation applications such as controlling helicopters, or cars. The gaming stick is for most games that require precision.
The ScreenStick will work for most games that already have a virtual joystick and they don't look like they will be too costly when they begin shipping, coming in at $24. If you're serious about your tablet gaming then I recommend you pick these up.
