Perfect for Arduino Clap Switch
Works great with my Uno board. Sensitivity is easy to adjust using the small screw on the board. Highly recommend for beginners.

Great whistle switch
Used this to control a relay with a whistle. Very responsive and stable output signal.

Okay for beginners
Works but documentation was sparse. Had to look up wiring diagrams online to get it working with my ESP32.

Good value
Solid module but took some time to calibrate the potentiometer correctly. Once set up, it responds well to claps.
