Review on 🎮 8Bitdo SN30 Pro Wireless Bluetooth Controller with Joysticks Rumble Vibration USB-C Cable Gamepad - Enhanced Compatibility for Switch, Windows, Mac OS, Android, Steam (Gray Edition) by Chris Long

This is the perfect companion for your Raspberry Pi with RetroPie or Recal Box. Exact height and width of the SNES controller but slightly thicker to accommodate L2 and R2. The analog sticks aren't as tall as their Dual Shock or Xbox One counterparts, but they're really good. Also very well built. I rarely had to charge it either. The battery life is very good. The only thing I wish it had was six buttons on the face and four buttons on the shoulder so it could be the perfect Sega Genesis controller, but that's the norm these days. It handles everything else well, including dual-stick PS1 games.
