Great for prototyping
Saves time not wiring up serial monitor. The LED display is bright and easy to read during initial tests.

Decent but basic
Works well but wish it had metric toggle. Default units are fine but flexibility would be nice.

Accurate readings
Compared to tape measure, very close. Stable readings in indoor environments.

Good value
Display is bright, pins need soldering. Works well for checking sensor functionality before integrating.
