This Air Conditioner is really one of the best you can buy. You would be hard pressed to find a bad review on this brand. This particular model works perfectly right out of the box, I just set up the exhaust tube, plugged it in, and it was cooling my large bedroom in no time. I bought this model to replace a Hair air conditioner that just didn't live up to its stats. This Whynter model lives up to its reputation and does what its supposed to do, cool down your home on a hot day.
