Very good product. Runs very quietly with little play. The reason I chose SS is because I had a non-SS a few years ago and it was done sloppily with a lot of movement in the movement. It's been many years and to be honest I don't know if it was made by DE-STA-CO. In any case, I wanted more precision in this style for the project I'm using it on and I'm very happy with it. I would buy it again if I needed another one.
