MJR Tumblers Single Barrel Rock Tumbler With Grit Media Kit - Polishing Tool For Adults And Kids Rock Polisher Machine With Grit & Plastic Pellets For Polishing Stones, 12 lb

The MJR Tumblers 12 LB Rock Tumbler has been awarded the Best High End and Most Versatile Run 4 Dif Barrel Combinations. The tumbler comes with a great warranty. However, customers have faced issues with stones getting stuck inside the tumbler, which can only be pried out, and the cap made up of black rubber which rubs against the edge resulting in rubber filings all over. A customer who kept the unit unused for over two months found out that the tumbler did not work when they tried to use it later on. Some customers have also reported issues with the quality and durability of the components of the tumbler.
