I'm a very keen paper crafter, make lots of greetings cards. I've wasted money on all sorts of fancy expensive cutters, one did circles as well and was awkward, another needs magnets to hold down the paper and is fiddly, 3 others just wouldn't cut. I found myself coming back to my first paper trimmer time and time again, v similar to this one, which was virtually worn out, so I went on Amazon to find a similar one. This is great, simple, works,just takes seconds to use.You just put paper/ card on the grid and check it's on there straight- both lengthways, and across, hold it down and press and pull the cutter, but that will be really obvious. It just has the one attachment, but like I say, I didn't want more. Self healing mat good too. Been usuing it regularly for a few weeks. I prefer punches or scissors with cerrated blades for fancy edges to paper, much simpler to use in my experience, (and I must have made hundreds of cards, no exaggeration). Great product if you just want to do basic cutting.
