I have a T-mag I bought over 20 years ago.
It was accidentally left out in the elements in a cardboard box during a move last year (thought that pile was all trash) -- for several weeks.
A few minutes a day for a week or two with some PB Blaster... good as new. (Lost a couple dies, though).
No reason to replace it, it does everything I need. Doubt my sons will wear it out either.
