Review (4/5): Great for a guide.
I bought this because I can never get the perfect cat eyes. I got this hoping it would help. And it does! You definitely have to play with it and get use to using to the fact that the cat will sometimes block one eye when using it. The one problem I do have with it is the parts where you would actually trace the cat eyes are not as pointed as the pictures show, they are more rounded which was a bit disappointing.
