Pros : Beautiful when it works the way it should.
Cons : I was trying to cut strips that were 1/2" wide and 3" long. It was difficult to do by hand and get consistent results. The streamers sometimes popped off, and the glass often did not break along the lines I scored.
Other Thoughts : Fortunately, I was cutting the glass for icicle ornaments, so the pieces that did not break along my scored lines were still usable as decoration on the icicles.
