Great tumbler
4 Stars
Great tumbler
Works well, just wish the plastic support sleeve on the shaft which turns the barrel was easier to replace/adjust. It started sliding toward the motor and fraying. Had to cut it off, trim the end and tape it back on with electrical tape. Every day I have to center it and replace the tape every month or so. It works like a champ though.
