I agree with you Baal about the "special blades" (I don't think they are original) but for ordinary blades the price is similar, a bit less than other sites, so I think that they are original...
For shorts and t-shirts I don't trust them
Thank you very much silent rain and stanny for the descriptions made
Are there any other opinions from other users?
PS I think I will buy this blade by your description stanny, probably the new version but I am non 100% sure
