How lond do SPD cleats last?

[Panter]

Apolgies for yet another of my "piece of string" questions but my right foot pulled out of the M520's a couple of times last Week.

I still have the pedal resistance set to minimum from when I first went clipless and had never tightened them as I never felt the need.
Anyway, I've wound the adjustment screws 180 degrees and had no problems since, do I just keep tightening these down down when my feet pull out or should I think about changing the cleats?

I've done very little walking in them so far (furiously clutches plank of wood and refuses to let go.....)

They last quite some time - probably lose !

My various cleats and SPDs are all over 15 years old - say 15000 miles for the most used - and still work just fine.

just tighten them up a small amount at a time
