At last a portable aircon that works! – Thank you so much to the inventor of this product. He has thought of everything. We live on the Gold Coast/Australia where the humidity can get really high with exhausting heat for a very long time. We were getting very nervous about entering into another long humid summer but I don't think we will have a problem at all. We tested it on a hot day and was amazed at the cold air that came out of this very small & stylish Unit. Easy to move around as the castors run smoothly and a nice long cord is provided too. Its a nice compact design, so it doesn't take up much space, super quiet too. We are very impressed with this unit and will be recommending it to everyone.
