Good fun to build
This kit is great but some knowledge of electronics would be required as there are no instructions and you have to follow the legend on the circuit board to know where the components go and care would be required for the polarised components. The kit functioned excellent and although itβs not exact the distance measured is with in a few Centimeters.

I worked when completed
Easy to assemble, I want a project I could do to with the free time I had and it was fun to build, although it doesn't like angled walls much and you have to allow around 1" to 2" at the front of the device to get a good measurement, its a good project to complete.
