Review on 🎮 Enhanced Gaming Experience: ECHTPower Wireless Pro Controller for Switch/Switch Lite with 4 Extra Programmable Buttons, Long Battery Life, Turbo Function, Vibration Feedback by Russell Robertson

The function of the turbo button is poorly documented due to translation errors. Here's how it works for this particular controller: 1. Press and hold the Turbo button.2. While holding the Turbo button, press and hold the button you want to spam.3. You can release the Turbo button now, but you still have to HOLD the button you want to spam. press the "Turbo" button and release it to spam at the touch of a button, and then press the "Turbo" button again to stop spamming. Otherwise the controller is what you would expect. Great as a cheaper alternative.
