I have recently discovered that the patented "Lift And Cut" system that is found in many electric shavers these days is halakhicly controversial amongst the Poskim. Some permitting them and some forbidding them. The more I read on the subject, the more I get confused! In your opinion, are the shavers halakhicly acceptable?
"Halachicly controversial" is, indeed the key phrase. It is impossible to say, in a blanket fasion, that these shavers are allowed, especially since we are dealing with a Torah prohibition. There is a possibility of taking out a part of the shavor to make it more acceptable - see http://www.koshershaver.org/faqs.htm
