Pros : Beautiful beveled hummingbirds. I bought 2 sets for two windows. They turned out really nice.
Cons : My set didn't fit very well, that happens sometimes. I was able to grind them to fit them better. They grind down easily, don't be heavy handed.
Other Thoughts : I used the beveled hummingbirds in a window with Bullseye confetti glass. It looks like the birds are flying amoung vines with flowers. So beautiful!
