Beautiful appearance. Not much to see inside as my speed choice is one. Not sure if it's slow, medium, or fast, but that's about it. I would contact support before writing a review but don't know how to find it. No email or phone for instructions. Google search was empty. TO UPDATE. I keep experimenting and now believe I have all 3 speeds, it's just that they are slow, slower and slowest with very little difference between them. But for tight work, it's very cool and smooth. Reasonable (more than) price for what you get. However, the apparent lack of any kind of customer support remains a major downside.
