“I'm not expert, but this gamepad satisfy me. Already tested with PC Windows and Android smartphone. Still waiting for Raspberry time. Just wondering is rechargeable AAA compatible with this gamepad?”
“The case is smooth, nice-looking; all buttons operate well. No problems with pairing and button defining @ Retropie. However, there is often issue with wireless channel, which from time to time disappears. As result, in the middle of gameplay, controller just gets unresponsive...
3xAAA battery compartment is big enough, to make a hack - using small Li-Po with some 3-D printed parts isntead of 3xAAA, which makes recharging of accu simpler.”
“The layout of this wireless, Pi-compatible gamepad matches that of a PS3, with the same number of buttons, plus a 'turbo' (autofire) button. It pairs automatically with the included USB dongle. The sticks are responsive and so are most of the face buttons, although the shoulder buttons are prone to sticking somewhat. Overall this is a solid choice for gaming and/or emulation, although I'd like to see more durable and responsive shoulder buttons.”
