Wuao!!!  I purchased this portable AC for my porsh which is in screen. I do have a few fans as well. Before We could not stand been in the porsh for more than 30 min due to the heat. Now, last night I turned ac on and fans and friends came over. We were 9 people from 5pm til 2am and everybody was amazed of this ac. Thank you... it is worse every pennie.
