I've used this thing for years and it had worked wonders keeping my 1940's bungalow cool. We had a brownout last year and the thing seized up. I got it running for a few more days, but then there was nothing else I could do as the motor was blown. I bought an air conditioner to replace it, but it's not the same. The electric bill went up and the AC is annoying. Sure, the AC will be useful when it's constantly in the upper 80's at night, but for most summer nights in Michigan, this fan fits the bill perfectly.
