I needed a rotary to do optic cuts on slides and other circle-like shapes and found this one by searching on Google. When I saw the price I bought immediately as I don't think there are any cheaper out there and this one arrived in great condition. Everything is smooth and well built. The backlash is the same as all the other rotary tables I have ever used so no surprises there and the machines surfaces are beautiful. The table comes with way inserts for faster setups and looks to be one of the best deals on a machine tool I have found to date. Thank you.
