I agree with Wingman. The stuff works great, but you do need to be careful. If you clean primed cases, deprime them quickly. Mine didn't break a primer in half fortunately, but I did have a lot of corrosion in the pocket, even after a good rinse.
I have since upgraded to a tumbler. I have a smaller model made by Midway and I wouldn't go back. It's nice for me because I run it on a small plug-in style timer. I set it to run for an hour or so and go to work or whatever, unplug it later and leave the cases until I've got time for them.
