Bests & Worsts Reviews from Amazon

I was ready to buy this RQ11 replacement head for my Sensotouch 1150x 2D shaver when thanks to another reviewer of the RQ12 replacement heads I learned that the new RQ12 3D was a direct/perfect fit replacement upgrade from the RQ11 on my old 2D shaver. The RQ12 is a real advance over the RQ11 because each of the three blade pods flex not only to the inside, but also outward, each independent of the other. A much better shave, even on tough neck hair. My old 1150X 2D shaver is now 3D.
