Solid performance

Accuracy is good for the price. Had to tweak the gain settings initially but once calibrated, it's stable.

Easy to integrate

Documentation could be slightly better, but the pinout is standard enough. Distance readings are consistent.

Great versatility with interfaces

Love that I can switch between I2C and UART depending on my microcontroller. Works perfectly with my ESP32 project.

Good range

Works well indoors. Outdoor wind noise seems to affect it slightly, but that's expected for ultrasonic.
