This is considered a very basic model for rock tumblers. One 3-pound capacity barrel and a drive motor. Has a very good leak-proof lid-retainer system. Most people start with a single-3 Lb. or a double-3 Lb. rotary rock tumbler. Great for small loads, and while you are learning--it is also very economical to run. It will achieve the same polish quality as the others. The Lortone name is considered the gold standard for rotary machines.
Note: this is a brand new rock tumbler which carries the full factory warranty!
