It works as expected. It cools my room (250 sq ft) effectively. However, it is very noisy (as expected). The draining location is very low (very close to the ground). It will need some boosting before I can drain it. The assembly is relatively ease. The product works good but the delivery is poor (zero star). When I received this unit, I noticed there was only 1 strap on the unit and it was kind of loose. When I try to move the box, the bottom of the box fell off. When I opened the box, one of the windows slide was broken, I found that small piece on my driveway!! It is very obvious to me the deliver was not up to any standard. The unit seems to be working fine regardless.
