I got a JBJ Artica used on Craigslist last year. The guy I got it from said he had it for almost two years with no problems. I'm probably 9 months with it now and still no problems. Worked like a charm and I'm out in the Palm Springs area, so we get really hot in summer. Did not notice any increase in electric bill either, in fact might have gone down just a little over summer. I've heard some people mention how much more these cost to run, but after purchasing, I was able to not use our AC
as much during the day while at work, so it probably saved us a little overall. Before, I had the AC
on to keep the room temps down during the day.
