i got the cordless one at RCW recommendation. it really works. I love it and it was worth the bucks. my skin may not be perfect but it has never been this clear even when i was using proactiv. i dont use any cleansers, just the ocm. i have used real afircan black soap. my skin was super soft and seemed cleaner. but after about a month or so of using it i broke out horribly. after a week or two of stop using it, my skin slower begin to clear up. i will use black soap on my hair, but nothing else. NO WAY!
