I bought one of these trimmers a couple of weeks ago and I find it to be a lot of trouble. The guide wiggles back and forth making it very difficult to make a straight cut. You have to hold the guide down really hard to prevent it from moving and that makes it difficult to hold the paper in place while cutting. If people had three hands this would be easier to use. It's inexpensive, that's why I bought it in the first place, and the one I bought came with a very handy pair of scissors.

This ia a really GREAT product - it is inexpensive but it works wonderfully. The blades give a crisp cut easily. It is small and light making it easy to store and carry. I would highly recommend this to crafters!
