A friend of mine has this and loves it. Says it saves her fabric as well as headaches with things not slipping. I saw the same demo at the same time she did and was quite impressed. The angled cuts are far easier with this than using your ruler. I did not purchase one and have resorted to a few other resolutions for clamping things in place. Overall I think it's a great product though. Do check around some online places though. I have seen them being sold used in a few rare instances.
