AC was less expensive than the 6,000 btu one by Frigidaire, it cools our bedroom off quickly-no need to turn it on an hour or more earlier like our old one!  Not as quiet as I would have liked, but quieter than our old one.  Part of the issue is the cycling on and off, I would prefer if the fan ran constantly, but it shuts off then starts back up which can wake us up.  Overall happy with the purchase.
