I got the kit from stm and it works great. Done probably 15-20k worth of brass so far.
I fill it up with the pins and brass till it is only 2 inches or so from the top. Bit less at times but I've found it cleans just fine up with that many. Then fill it with water till its an inch from the top. Pinch or two of lemishine and a squirt or two of dawn.
Tumble for an hour or two and then be done. I pour it in a media seperator, wash thebrass, then dry the brass. The pins I pour back into the canister and then just wash them a couple times and pour most of the water out. Then close it up. Takes about 5 minutes to do.
