Review (5/5): Best Money I Ever Spent !
I bought my 7700 series electric razor several years ago and don't use it every day but I was noticing the shave was getting less close. Instead of buying a new razor, hundreds of dollars, I bought these heads which were a snap to change out and I feel like I have a brand new razor, man what a difference and Amazon is just about the only place you can find them. Don't even look anywhere else, just order them here and by the end of the week you will feel like a new man or woman depending on what your shaving !
