This item is great! I use it for my bedroom and I will freeze and have to turn it off. My room is large but it could easily cool another room too!!

The air conditioner works great, is quiet, and has good controls. If the window to hose connection went together easily, I would give it a FIVE star rating.

It puts out lots of cold air but only one button works on the remote. Also seems like the connection between the hose and the window guard could be much stronger, it's pretty flimsy and pops out at times.

Seems to be a good A/C works quietly to keep room cool and at consitent temp. Instrustions vague and not explained well or in enough detail to fully understand the operations. Still guessing and expermenting with the features.

Bought this item last year. Worked great. We put it in this year. Worked for just over a week. All of a sudden nothing. The power cord test/reset button lights green. A/C wont power on.

I live in Southern California, and with the summer heat hitting the high 100s this portable AC has kept my 450 sq foot master bedroom cool. I've had this AC for a month now and have been using it everyday without any issues. Assembly was easy (did it myself). I like that I can control it with it my phone, and it cools down my room fairly quickly considering the size of my room. Overall I am happy with this purchase.

In North Alabama we have had over 60 days of over 90-degrees F, with over 20 days over 100-degrees F since mid May. Our Garage was heating up to the outside temperature and was unbearable before we got this Air Conditioner. Now even during days that get over 100-degrees the Garage heats to only about 80-degrees F and overnight it cools down to about 70-degrees F, so we can actually use the garage for woodworking, grooming our dogs, etc., without raising our Electric bill much.

Much better build quality that other portable AC units I've seen, particularly the window exhaust adapter. The controlled make-up air, the "duo" from its name, is a strong selling point. And the "sweep" mode for the supply register is a really good feature for mixing the air in the room. Though lacking on the actual details of the variable capacity provided by inverter compressor speed control, the concept is well established. Like all portable AC units, its major draw back is that the condenser is in the house, i.e., it's not a split system. This characteristic makes all portable AC units less efficient than window AC units. For the same reason, portable AC units do not control humidity as well as window units.

Powerful Ac. Keeps our bedroom cool. It does make some noise but much quieter than the other two portable Acs we have around the house. It does use a lot of electricity. If we have a lot of other stuff on the breaker will trip. Overall I am happy with what I paid for.

Central AC went out so we were in a bind. Bought two of these units because I didn't know if one would be enough. Ended up only needing the one. This is my first experience with this type of unit and it exceeded my expectations. Not difficult to set up and it cooled our living room and kitchen really well. With the help of fans throughout the rest of the house it helped those too. Only thing I would change for the future is that I wouldn't use the adhesive, flat, insulation tape/pad. Instead I would use the thicker, non-adhesive insulation to wrap around the unit as well as filling in the gap above between the two windows. I only used the unit for a few days, and as a "portable" unit, the adhesive isn't transferable and is difficult to get off the window sill.
