I've been looking for a circular affordable cutter that goes through different types of paper. Unfortunately, this is not the one. I returned this product upon arrival because, although the design is good overall, and the price good, the production of the design is poor.
THE GOOD
Very light and easy to use. Put the round body on the center from where you want to cut. Adjust the small button tip on the ruler to the diameter of the circle you want (it loses and tightness by rotating it), and then rotate the long ruler around. Perfect circle cut. It works like a flat compass.
It works especially good with normal paper, like printing paper, but it's also good with thicker papers like 200 gsm and 300 gsm watercolor paper, which is what I wanted it for. Needless to say, I had to press quite a bit for the thicker paper to be cleanly cut; when I did not, it left paper traces and unclean edges behind.
The round body has a container in the belly, protected by a lockable lid, where two complimentary blades are located.
THE NOT SO GOOD
The circular part is toy-like, so no weight at all. That being the case, the platform slides off center often creating unnecessary cuts and ruining the circle I was cutting. This happens also when pressing it down with my hand. I would not press it too hard because it's average plastic. There is nothing attaching the round body center to the surface, that's the reason it slides.
This is great for large circles, from 8 cm up, but not to cut smaller circles as the small adjustable knob stops against the circular body at that distance.
No instructions on the box or inside. The cutting blade is protected by a cap that can only be removed if slid on the side, not up. It took me a while to figure it out. You might break it if pressed up too hard.
You need a large surface, with no clutter on it, to rotate the cutter easily.
Very weak plastic.
