      I researched several different brand and models before deciding on the Keystone 550 Square Foot air-conditioner. Out of the box there is little to assemble and I had it up and running within 15 minutes. Cools extremely fast and has all of the extra remote control features I need. Works better than what I paid for. Very happy with my purchase.

      Great portable AC for the price

      Easy installation and cools sufficiently. I needed another portable AC since my Condo Association doesn't allow window AC's. I purchased a Sharp product from Costco 5 years ago for another room and it is still running. Didn't like the Delonghi model sold at Costco. After researching reviews and price I decided on Keystone.

      Missing part and poor service

      Unfortunately, I never got to try this a/c. It arrived without the window slider. Best Buy was out of stock so I was told to contact the manufacturer. When I finally reached them, they sent the part to the wring city. I had them reship, and the part that arrived was the WRONG part. I finally got fed up and returned the whole thing.

      Airconditioner that really cools!

      This air conditioner is something that really does cool. Though because of my NYC apartment I wish it had more versatility in how it plugs and is positioned with the window. Also the tube that connects to the window is very stiff so it is not nearly as mobile as the ad described. However, I love it and it has made this summer livable!

      Works great. Cools my room. Don't kid yourself, No air conditioner is quiet because ALL air conditioners have components that are GOING to make NOISE. My only complaint is that it doesn't have the water line that disperses the water along with the hot air. Getting rid of the water is a bit of a chore. Other than that, it's great.

      I returned this unit for an upgrade. It was delivered with a crack in the housing. I returned it and the next one was delivered with the back smashed. Now I have to return this unit. I’m sick of getting damaged merchandise from Best Buy.

      At first I thought I was going to return the product before I'd even open it. To my surprise once I had it all set up I was wonderfully surprised at how cool it got my room so quickly. I love the air conditioner.

      This portable has a high BTU rating and has great features all at an excellent price point. It's relatively quiet and portable and it moves a lot of air. You cannot compare portables to window mounted units but if you don't have mounting options, this is a good choice.
