In all honesty, I haven't used it for 40 years so I can't really vouch for it's lifespan, but I did use it in a helluva rainstorm in a humid climate and the 60 took it like a champ.

It's very good at rejecting unwanted sound, but still has a more forgiving pattern than the 416. Combined with the rolloff and pad switches, I think this is a great, an under appreciated mic from Sennheiser.
