I can’t say that I use this a lot but I would not want to be without it. I simply don’t use a lot of circles or ovals, however when I need them this is the perfect tool. There are other shapes that you can purchase to go with the system. I primarily use the circles. The template allows you to place over a photo and find the correct size you want to crop. The color of the blades correspond with the colored lines on the template. Tips for use: make sure you remove the template before cutting so you don’t cut through it. I find it easiest to use if I am standing up.
