I have to return this just on the level of noise alone. It is not possible to work and use this air conditioner in the same room. It will drive you crazy. The bigger problem is that you need to have it very close to you to keep cool. it does not spread around the room fast at all. that makes the noise much more of a problem.
I did some research before selecting this unit, and I'm satisfied with it. It's not too noisy, has good airflow, and it's easy to set up and get running. The exhaust plate was easy to put in our standard window - just had to take the screen out. Best part is that no one can tell there is an AC installed in the window from the outside. Good product, very satisfied.
Easy to setup, easy to operate, cools down a small room very quickly (225 Sq.Ft to300 Sq. Ft). It is a little to noisy, but for the purpose, it will bring the temperature in the room down from 85F to 72F within 15 to 25 minutes. The size is very good. I have to place it on my work desk to allow the vent to exit my window which is above my work desk. The ac unit comes with a exit cut-out window adapter and a vent hose that is flexible to fit most any setup. The unit is easy to move and is well made. I would recommend this ac unit to anyone who wants a quick set-up at a great price.
