Good quality module
Solid build quality. Had to tweak the gain settings in code but got a readable waveform. Fast shipping.

Works as described
Sensitive to noise, so shielding is important. Otherwise, it performs well for the price point.

Great for learning bio-signals
Works perfectly with my Arduino Uno. Signal is clear when using proper electrodes. Note: This is for hobby use, not medical diagnosis.

Reliable sensor for prototypes
Used this for a university project. The lead-off detection is a nice feature. Clean output signal.
