Hmmm. Someone is always trying to throw a wrench in the act. I don't know, I've not been impressed with the vibratory thing. No matter, the dry medium is either going to have to be cleaned or replaced. One Minus. And it doesn't get the primer pocket or the inside of the case. Another minus. Noise and time seem to be another minus. Only plus is I've got the Lyman vibratory thing. Think I'll go with the chips.
