Pros : This circle cutter with the rotating carbide cutter head works FANTISTIC! The suction cup mount holds great on my Bullseye glass (which is not always smooth) without moving. The rotating carbide head is a must as the carbide wheel is always inline with the cut, which gives a better score. The bar has an accurate ruler on the side for easy setup for any size circles. This is the easiest circle cutter I have ever used, well worth the money for a quality tool, that will last a lifetime!
Cons :
