I bought the rotary cutter Prym because I had no desire again only to buy a cheap product, in the hope that it works, and then I have to re-establish that he is total garbage. I'm super happy with this rotary cutter and can no longer think away it to me. The most difficult tasks which he had so far were 2 layers of fleece and 2 layers of terry cloth and has really worked out well! Jean simply and 2 subject was garkein topic! At last I am able longer just pieces of fabric cut (this, however, it is recommended to take a ruler to where you can lead the rotary cutter long!). It takes a little practice, but that is almost all that. What I have to say, smaller parts I cut further with the scissors that I get with the rotary cutter is not as good towards (but that may be due to me and my nonexistent patience).
