I have not but i know 'snake lab' does and does (use and recommend it) I have heard good things and it is free of some of the nasty possibilities that have been associated with P-A-M.
I have only used the hard work method to rid snakes of mites.
I had bought a collection last year from someone who was getting out of snakes. I bought the collection solely for a couple animals and planned to sell the rest. When i picked the animals up they had mites. Not a full blown crazy infestation but bad enough. I used reptile relief on the collection, the racks, and myself lol. Mites wete cleared up quick. Pam is very effective but its because of toxic poisons.
