I bought an injector on e bay and loaded it with store brand injector blades from rite aid.
The shave, in comparison to my standard shave of Merkur HD with Astra Superior blade, felt sharper and closer, a tad rougher but with less red bumps.
I know there are injector blades by schick and personna. I also know people try cutting down feather pro guard blades and using them. I tried that and couldn't get it to work.
So those of you who use injectors, what are your favorite blades to load it with? This gave me a REALLY close shave, need more mileage to determine if better than the HD...
