It's actually not that bad ,messy and dust free
I built my tumbler and it uses two 1 gallon Coleman cooler(1/2" PVC for agitators) so I can tumble i large batch of brass or two seperate calibers.
My routine is I load up the cooler then run it for an hour. i then pour out the water( but not the pins and brass( it's not critical to get every bit of water out) I then reload up water and cleaning solution for another hour.
I empty the cooler into and then crank to separate pins from brass then quick rinse with hot water
I then spread out the brass on food dehydrator trays and run on low heat for 20-30 min.
There is no toxic dust as everything stick to the water.
So range brass pick up
After cleaning( primer pockets also polished)
After seeing the price of a tumbler vs capacity I've got CAN$100 into this one ( I can also tumble my steel SCUBA tanks ). Capacity ( per each cooler) 9mm=500pc,.45ACP =375pc, 5.56mm=275
