First of all there is no posting. I personally brought it in to get checked. Second of all, we are talking about a Braun which doesn't have lift and cut. Third of all, R heinemann of the Star K says that Lift and Cut is not the problem and you don't need to remove it. The problem is when the blades are too sharp in which case they need to be dulled. Don't just post chumras, learn the facts.
The problem with lift and cut is that that it pulls out the hair when it cuts (
lift and cut, lit.) and dulling the blades will only cause more pulling out hair which is the issur of lo tashchis, so that's not the solution.
A lot of poskim say that foil shavers (Braun) are too close to the skin and are ossur.
