Yeah you get what you pay for....for the most part.
I use SCHICK HYDRO 5, one blade for a month, because I shave Monday, Wednesday, and Friday.
I watched that blade cleaning/sharpening video below that is interesting and it does make sense, although the debris building up on the blade would be on top also, so how would one clean that area?
