Minox question

[Not giving up]

How true are the minox expiriy dates? I have one saying it expires a week ago, seems to be doing just fine still. It's from the belgravia centre in London and I'm just using it because I have it left over.
Any thoughts on how long it should stay good? Expiriy dates are always a bit drastic.

Bump.

It's fine at least 3 more months
