I just ordered one. I have 1 early 3rd gen that is really stubborn, to put it mildly, to get out. This gun is super tight and mechanically flawless, clean crisp clicks when rotating the cylinder but a real pain to take apart. I didnt want to spend $50 on a puller, and I'm tired of using a roll of electrical tape and pliers every time I want to clean her, so this looks like the perfect answer. I'll post again when I get it and try it out.
