Product line with what I have read. We find the "comfort" of the NES controller of origins. USB connection to PC very functional. Bluetooth, a Galaxy Fame Lite, it works well. But the equipment is quite complicated (you have to choose a virtual keyboard FC30, instead of samsung virtual keyboard). The app offered by the builder does not work with my version of android (4.2), but is on. RetroArch does not recognize the controller while it is listed in the options. Fortunately, others are moved much more tolerant. Successfully tested on complimentary moved GB, NES and SNES. The stand is nice, and hangs well, even with a holster V.
Also tested on WiiU via Punch Out Wii (I like to complicate my life). A slight delay but manageable. Useful for troubleshooting a joystick at parties in multi. Note that the A and B buttons are the buttons X and A. No worse for the thumb.
Notice the careful packaging if they wish to throw it away.
