Cools ok for what it is. It's as loud as any other low-cost unit. No problems there. HOWEVER, I'm in a very humid climate (swampy part of Florida) and must use the upper drain fitting so unit doesn't shut off 3 times a day due to full tank. HERE IS THE PROBLEM- -  The thread on the fitting is weird. How hard is it to design it with garden hose thread? Why the odd thread that I can find nothing at the hardware store to seal up to? Why is no accessory or adapter offered? I have several of this style of A/C unit by various brand names all use garden hose thread - the GE one is practically useless if I can't hook up a drain hose that properly seals, so I probably won't buy a GE in the future.
