One thing though get the flower pot attachment or put a 3 sided plexie glass container around the spinner so you don't dirty up your house. This is one of the benefits of my Haus is I don't dirty anything up. My balls stay round. It does a great job polishing and sanding. I'm just looking for a good way to clean my balls and I'd be set.
For the money though, I agree the Vertex is the best personal spinner on the market. On a hard flat floor there's no vibrations. Just get a good sturdy work bench for it. The basement concrete floor will never shake on this.
