Worked great for a small ac until we got 2 weeks in and then the vent arm broke off (might i add all by itself, it happened in the middle of the night while sleeping). Its pretty loud for a small unit but nothing that I can't eventually tune out.. now I'm in to a month of use and again, woke up to an extremely loud noise coming from the ac, like a huge rattling noise, so loud it woke everyone in the house up. Who knows what happened ,but had to turn the ac off and can't no longer use it. I live in Texas and def have to have an ac and now I'm getting the runaround on the protection plan that I purchased, saying I never purchased one when in fact I have an invoice showing that I did.. totally disappointed
