Defective 5 out of 5. Unfortunately, my money was wasted. Very powerful wheel but its durability is 2 months of use. Since I got it, I changed it twice and repaired it twice with my own expense. Of course, the wheel doesn't work after 1 year.

A great machine! I use it in my dental laboratory. It works without vibrations. Sturdy construction. I don't use it every day. It will show over time because I recently bought it. Anyway, I got it here more economically than eBay and others, and also without the hassle of customs, etc.

I do not recommend buying it, it can break within three days and within a few months!

I bought two wheels last year. They broke within two weeks. The excuse was that we don't know how to use the machines.
We returned one of them and it came back with the same problem, that is, the left turn suddenly stops working while the machine itself quickly heats up.
Unfortunately, it was a waste of money.
