My mom and I both have the cutter. It is great! She just bought a ruler at Paducah. It looks pretty amazing too. Grips the mat (any mat,) fabric doesn't slide so you can measure, then move and still cut accurately. It also has 1/2" to 4" slots in it to cut binding or strips perfectly. Pretty cool. I recommend the smaller cutter. You don't really need the big one unless you do industrial quilting! The small one will cut through 64 layers of material! Yes, I said 64! Get the big one if you do a lot of flannel, etc.
