Pros: Really effective at temps below 95F; Way cheaper to run than central air (but variable flow mini-splits might be closer).
Cons: Noisy; Sucked in dirt & dust from outside; The closed metal louvers didn't provide any insulation in the winter (so we had to put an insulated box over it); Didn't help much when humidity was sky-high.
Might be a good option for overnight cooling in a house with battery-backed solar (would have to run the numbers to see).

I grew up in a house that had one.
