Feather SE blades

How long are these blades suppose to last? I've been using one this week in my Valet razor and in started getting dull after 2 shaves.

I'm not sure how many laps I'm suppose to strop it either.

Feather spineless blades for the Valet & OneBlade razors don't have a great longevity. Many people seem to stop after 2 shaves like you. I got 5-7 shaves from them, but don't take that as a likely #. I can get 30+ from the GEM SS PTFE & Feather AC Professional blades.

Yeah me too I with I would have known this before purchasing them because 2-5 shaves doesn't seem worth it.
