yep, 4 blades a year and no issues.
People tend to seriously overdo blade replacement (used to as well till my dad told me I am doing it wrong).
I don't use shaving cream and that may also be why my blades last so long, the stuff gunks blades up like crazy and glycerine soap works about 10X better.
4 blades a year and no shaving cream!
Hellboy, is that you?
