Fail

Like the idea & wanted it to work so I could buy upgrade.

I fiddled with trying various heights to see if I could get measurements that were remotely accurate (definition: within 20%) - never could.

Tested with tape measured distance of 16’ and 40”
Never could get closer than + / - 5’

With all the 5 star raters for previous version I figured it has got to be something I am doing.
Tried again on another day, same wildly inaccurate results.
