As soon as one has a rotary cutter, one wonders seriously, how people lived before without. Cutting of small parts that were always friemelig else, now go ratzfatz so I eg again like sun hats near. I also have purchased the product but especially because it still had the prongs things here and I wanted to give up buying an extra Pip fabric scissors. Works great so far, primarily I use now but the "normal" knife. This in turn goes well so far. With a bit of pressure (I eh aufwende, so that the material underneath does not move), I'll be quite easily by 2 layers of cotton fabric. In some places I still have time "recut", but then is precisely because I was at the press schluddrig. Small Macke with my device: I have to screw every now and again to follow suit because it dissolves. Nothing dramatic, but one probably worth mentioning.
