The iMpulse is the world's smallest wireless mobile controller for all devices. This control works seamlessly with any iOS or Android-powered media player app from up to 100 feet away. This tiny unit is designed to fit comfortably within your finger tips allowing you to still obtain a good grip for portable gaming. Some people still prefer the use of buttons for their touchscreen devices so this controller would definitely come in handy.

It also fits within a key chain so it won't clutter your pockets. The device is Bluetooth-operated and has a directional pad with seven buttons. There are five on the front and two on the back with a rechargeable battery that is good for nine solid hours of continuous play. This mobile controller is perfect for the avid gamer who wants tiny and accessible buttons to play.
