Good but learning curve

Hardware is solid, but setting up the anchor tag logic took some time. Documentation is okay but could be more detailed.

Decent but warm

Works well but the chip gets warm during continuous ranging. Needs heat consideration in enclosed boxes.

Excellent Precision

Tested this against a laser measure and the 10cm accuracy claim holds up. Great for indoor robotics projects.
