i have been purchasing schick quattro cartridge refills for years, since they first came out! they used to be good. lately, the past few orders i have made for these have been terrible. dull, and not doing the job they were meant to do. schick has gone down majorly in quality. i have spent so much money on these refills only for them to be useless blades which i have to throw away after one use, and even that 1 time of using the blade is not a close shave. i don't know why they changed the quality of their shavers but it's a shame since they used to be the best! i would not recommend these to anyone and i used to all the time.
