Pros : Great to work with, cuts well! It is a great asset to our studio!
Cons : Sometimes the pegs slip out of grid base -just have to be careful when cutting. Tiny circles (are kind of tedious, but do-able) Not as sturdy as a lens cutter for tiny circles.
Other Thoughts : I pride myself on how I hand cut circles, but if you have many to do or want a little help... I highly recommend this product!
