I got these as part of the 75 blade sampler and they're among my favorites. They're sharp enough to cut my hair off without tugging, seem to last well enough, and aren't so aggressive that I get irritation. I've used these blades with a Fine Superlite Slant as well as the V3A head. Will probably become my go-to blade when I'm through testing all of them, barring some miracle from Big Bens or 7 O'Clock blades.
