Excellent. I changed the "mother" disk on my circular saw and it transformed. It cuts melamine and plywood as if it were paper.

I have it for amateur use on a cheap Chinese jigsaw. After quite a bit of use, I only have positive comments. It cuts nicely and cleanly, it doesn't cause vibrations, and after several cuts it remains with an excellent edge. Especially on melamine, which I was afraid of, it cuts very cleanly without "breaking" it.

I can't believe how well it cuts white melamine without chipping. And it's durable and also free.

For its price, it is excellent. It has precision in cuts and leaves a clean cut in its passage. So far, the construction quality is excellent, now time will tell. Recommended.
