Review: Works great! - I was a bit leery after reading some of the reviews for this cutter, but had not found anything that sounded any better, and I trust this brand. Not a lot of instructions, but not a lot of moving parts, so "setup" was not hard. And it cut a perfect circle on the second attempt. Love the ratchet handle. The paper did bunch on my first attempt, but I taped the paper to the cutting mat second time, and that solved the bunching problem. I've cut a lot of circles since yesterday, and, like any other rotary cutting blade, this one is beginning to dull. Replacements won't be here until tomorrow - that would be my only suggestion here -- charge another dollar or two, but include a couple replacement blades. I did cut circles from very small to almost 8" (the max cut) without any problem, using both standard copy paper and a medium weight cardstock. Heavier paper requires more pressure, but it works. Tried it on a scrap of some cotton quilting fabric, and the result is a 9 out of 10, but with a fresh blade it should work just fine. This is a good product that does what it is supposed to!
Review: Perfect results in a fraction of the time! - This is a great time saving, end result perfecting product. I am a quilter and I have had numerous projects where I need to cut out circles. This cuts out all the tracing and cutting steps out and with a tiny bit a practice gives you perfect circles in seconds with little or no stress on your hands. In the past I have had to trace patterns then cut, or make a pattern and use a rotary cutter to try and cut it out. This saves time and the end result is much better. It is a simple enough concept but it works. I would have liked some simple instructions to come with it but it was easy enough to figure out. I do know some people who would struggle though. Make sure you have a cutting mat. I also took a piece of cardboard w/felt glued on and with a circle cut out to put over the fabric to keep it stable (it was a fair bit bigger than the cut out) . It improved my result because with very little pressure the fabric didn't shift. It is great when you can find a product that gives you exact results with little effort. This is one of those products.

### ⭐⭐⭐⭐ Practice, practice, practice!
*by A***E on October 24, 2025*

Well, this certainly requires practice. I'm using it on fabric that's 100% cotton and I don't know if it's the fault of the tool or if it came with a dull blade but it doesn't cut, even through single layers, on the first go round. I find I'm clipping parts of my circle with my scissors. I've watched a few Youtube videos for help using it, but still isn't as good as I'd hoped. I've always loved the brand so had higher expectations for this tool. Oh, and it doesn't hold the width in place--I keep having to move it after every circle even though I'm getting it as tight as possible. Tips welcomed!
