I haven't and won't because they test on animals BUT if they didn't, I would certainly try it. Alot of people are liking it, although they still contain menthol and peppermint oils which I don't really care for. It seems like those ones don't have alot of the nice, nourishing ingredients WEN has though.
I've tried that RENpure and one other one, can't remember the name, and they were absolutely NOTHING like WEN. I haven't tried the others like L'oreal because of animal testing but I haven't head good things about those anyway.
