The most difficult part of buying this replacement cutter was confirming that it would work with my Braun "Series 3" 360 razor. As other reviewers have stated, you should be able to read "32S" molded into the plastic beneath the trimmer attachment. (You will have to extend the trimmer to see this code.) This "pack" does not include a replacement trimmer, but you probably do not need to replace it at 18 months anyway. Also, this "pack" includes just one complete replacement head, so you may need another eventually. Hopefully this replacement will last as long as the original.
