Astra Superior Platinum (Green), 3 days.
Exactly the same experiences here!Astra SP 3 uses. I can and have gotten 4 and 5 uses out of them but it doesn't feel the same or I get weepers so I just discard after three (they are so cheap).
Funny because when I used to use carts I would use those things up to a month trying to get every shave out of the expensive suckers that I could. I would shave long after the lube strip was worn off.
For reference I shave every day.
