I saw this on a video and thought it was a genius idea. My husband and I do most things ourselves and had done hardwood floors in the entire house and tiles in the bathrooms and laundry room. Man, do I wish we would've had this back then for all the door frames cutting and the toilet too. We moved to another house with mostly carpet and are getting ready to do this all over again, but this time around we are getting mayor help with the countour gauge. We did a little trial test with a door frame, what a dream, after the cut it fit like a glove, no more cutting the same piece just bits at a time for a perfect fit. Just one measure, one cut, perfect fit, it doesn't get any easier. We are very excited for our project to begin.
