Good call.

Just recently, I had a bathroom fan in my office building die. It is the original fan, it last approx 64 years! And it's on a lot. It had a lifetime warranty from Dayton. They honored it.

The new one has a 3 year limited warranty... Same fan, same company. I'll 100% guarantee we don't get 60 years on the new motor. And likely it is 50x the price it was back in the 60s.
