Was easy to use, intuitive w/o reading directions, and it made perfect circles as I needed

It can draw an accurate circle provided you set it up properly and accurately

The screw and tension system hold the compass at a constant size for the most part, but the arms have too much 'wiggle' room and can give you messy circles if you put too much pressure on them when drawing

I made a nice 6" circle with it for a couple cornhole boards and it worked.

Very difficult to make a perfect circle with.
