I haven't tried it yet, I'm actually afraid to use it and even breathe on it considering how fragile it looks. There are no channels/speeds listed for this product on the website, just a "-" on the page where it is listed and at the top of the page there is a reference to page 78 which does not mention this product. The sticker says 'Made in America', but it's eerily similar to the cheap Chinese cookie cutters I used to have. I'm thinking of a 0.0002 load per tooth?
