A few years ago I ordered a Yonico cutter for the first time. I have a lot of joy and SMT. I only needed the bit for the one time use profile so figured I might at least get a pass from it since it's so cheap. Well I was surprised at its quality (it was a beaded attachment) and have since ordered a few more. In terms of quality, they are in no way inferior to expensive brands. Shouldn't be, but gee. I get miles from them. The carbide holds and the finish is like quality. With cheap bits, the paint often blisters and holes. The color doesn't matter, but it makes the product look better. For the bits I use once, they're fine. I think they will be suitable for longer use. It's nice to get a decent quality tool at a premium price. Recommended by me to all other carpenters out there.
