I "self gifted" this ruler for myself for Christmas and absolutely love it. I just used it for the first time and cut a lot of two and three inch strips for a charity quilt for my quilting guild. It really cuts easily, doesn't slide around at all and you don't have to press hard on the cutter.
It may not be for everybody but I find it very useful. WHen I bought mine it was 50% off plus there was a coupon for and additional 20% off entire purchase. If you don't have a receipt you may get a refund of less than you think.
