A long overdue follow up… My frequency of use with this razor has slowed, as the lure of DE beckons me every morning; I’ve used the Rx Injector on average of one to two times per week for approximately five months now. It is impressively smooth shaving. My favorite blade continues to be the Chinese Schick; and my least favored remains the Personna PTFE. Japanese made Schick branded blades with keyed dispenser, and the Proline B20 blades are highly usable, but for as long as my local pharmacy stocks the yellow pack Chicks, I’m going to stick with them. They just work for me.
