I'm actually thinking of buying a misting fan, anyone got one

Saw them the last couple of years while on holiday abroad in a restaurant which had an outdoor area which was covered and had screens around the sides but wasn't a sealed indoor area, hard to explain perhaps but think more like a tent / marquee
Anyway I saw what i initially thought was smoke coming out of this fan so looked at it and worked out it was mist / water vapour and every time i got a blast it felt cool.
In talking to one of the waiters he said that when they ran the fans it brought the temperature down by something like 6 or 8 degrees
