The head is to replace the 12/50. Have ordered him why. First impression: the old was with his folding mechanism more practical and high-quality. But what the hell, shave time. Dry: ok goes well, OK result, but also a new head, so it should be better than the old. But if I remember correctly it was the last change that way. Wet: it twinge, ups what's that, I do not know so, and I'm really not squeamish, so shave times over, whoever would be fine to suffer pain. But what did not work is the result. Only slightly better than dry, I know better. So same time ordered the old 12/50 and the 12/60 send back. I can see the "new" absolutely not recommended.
