Works great and was easy to install. The fact that it vents out the window and doesn't sit in the window is great. I would have given it a 5 star but the fan is a little noisy when going on and off as it adjusts the temperature to the thermostat. In air conditioning mode you don't have to drain, only if using as a humidifier.

I am loving this air conditioner! I have a small, fairly sound resistant music studio that I built in my garage that is about 160 square feet in size. I needed an air source and a way to cool the air. This air conditioner is just what I needed. In my case, rather than vending it through a window, I am vending it through a wall, but the concept is the same, and it works great!! I find it to be not too loud when operating, it has great air flow, and it is keeping me cool and refreshed. I am very happy and highly recommend this air conditioner.

I ended up having to return the unit because it would not cool off. It would blow hot air instead of cold air then when I finally got it to cool after making sure everything was on right again, it wasn’t actually cold it was slightly cooler than hot. I bought a different brand and it automatically came on cold. This told me that it was not me it had to be the unit

I bought this AC to cool my bedroom when the house central AC went out. I ran it on the coolest setting of 64 and it ran non stop but could only cool the room to 74; my bedroom is 300 sf so well in the ideal range. When I set a thermometer on the airflow it registered 64 but even with the blinds and thermal drapes, and door closed the room stayed at 74. I'm grateful as it has been a lifesaver while waiting for a backordered central AC. Sam's had a great price on it.

Visiting my daughter in San Antonio and every day over 100 degrees when her central air burned out. This efficient portable unit installed quick and easy. It was the perfect solution to keep the main room survivable during the week it took for main A/C replacement. My daughter will continue to use as highly energy efficient supplemental cooling.

We recently bought 2 of these portable A/C units for back up cooling if we lose power. They are currently plugged into our back up solar generator. We supplement the house A/C in the meantime with free cool air. My husband made stryofoam window fittings for the different sized windows so we can use the units anywhere in our house. Very glad to have them now and especially if we lose power.

I am more than pleased with this purchase. This is a workhorse portable AC unit and really does the job in an area larger than the advertised 500 sq ft. I own other Delonghi products that have lasted many years and I'm hoping this one will as well. My only disappointment with this unit is that the air flow direction is not adjustable. Also I do wish there was a better way to drain the de-humidifier unit as the tube provided easy to lose. (or maybe they could have a compartment to keep the tube in). I really don't used the de-humidifier though. Lastly, I'm not nuts about the typeface of the model stamped on the front, but that's no big deal.

Constantly needs to be drained from bottom port which is very difficult to do.

Love this brand! We have 3. Drain them at the end of the season. Very little maintenance.

Unit did not cool a single room 12x 12 below 80 degrees during the day
