iMpulse Bluetooth Controller
Touchscreen-equipped devices are beautifully versatile, but when it really comes down to it, a capacitive screen won’t ever fully replace buttons for tactility and accuracy. iMpulse gives mobile gamers a better option, cramming a D-pad, four thumb buttons, plus two rear-mounted shoulder buttons in a device only slightly larger than a car key. It conveniently communicates with your device using Bluetooth, packs a rechargeable battery that churns out 9 hours of gameplay, and a form factor that goes just about anywhere.
