Good product. the brass is clean as new. - Frankford Arsenal Reloading Tools Platinum Series Rotary Tumbler 220V

I can put 1000 5.56 brass in the tumbler, although it have to run a bit longer. I only put 4 stars because the O-rings must be tightened VERY hard to prevent water leaks during processing. It's a bit noisyier than my dillon 7001 tumbler, but wet tumbler don't make dust.
