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, 20 lb

The MJR Tumblers 20 LB Rock Tumbler has been awarded the Best High End and Most Versatile Run 19 Dif Barrel Combinations by an editorial review. However, it is quite noisy and not recommended to be run inside homes. It can be used with different sizes of barrels, and the base unit can be used with multiple barrels as long as the weight limits are not exceeded. The tumbler does not have rubber on the inside of the barrel. The lid has a 6" opening, which can fit one or two larger-sized rocks. The customer reviews indicate that the product is strong and has lots of space to load up, but it requires a hefty cost and requires a bit more maintenance than expected. The barrel tends to hit the frame and chew itself. Some customers also faced issues with the bearings, leading them to replace them at regular intervals. Despite that, many customers are satisfied with this product as it yields excellent results and makes tumbling large quantities easy.
