I wasn't expecting such a good quality. I used a smaller Milwaukee and the Vevor tool is a lot better. Not only does it have better replaceable cutters but it allows zero dust to escape. It catches all of it.
The only thing to be careful about is to keep the rotation speed as close as possible to the recommended values and, very important, keep the device perpendicular to the surface.
Top notch tool I'll recommend it to anyone interested in such a tool.
