Review on 🎮 AGPTEK 2 Pack NES Classic Controller Wireless for Nintendo Classic Mini Edition and PC - No-Wired Gamepad Joypad Supporting Windows by Curby Alston

Do not buy these if you intend to connect them to Raspberry Pi 3. In short, a very long, frustrating and boring story - Pi 3 does not fully accept these controllers. Any NES game that uses controls that include a directional button + A or B (that's pretty much ALL games) will not be recognized by the Retropie/Pi when using those controllers. For example, if you're playing Mario 3 and try to use the right directional key + B key to run forward, the system doesn't recognize it because it can't recognize the combination of more than one key press at a time. I tested 3 different controllers. With the Pi running Retropie, this particular NES controller is the only one of the three that didn't work. The other wired version worked great, as did the PS4 controller. This was VERY disappointing to say the least. These will be returned. Huge waste of my time.
