I ordered one of their Blaux Auxiliary Portable AC units and a separate water curtain on 6/4/21. It didn't work so I Email'd them requesting a return label. They eventually responded advising me they don't provide return labels and the return shipping was my expense. I advised them that I had filed a dispute with my bank and would be finding any place available on-line to review their defective product and horrendouscustomer service. User's recommendation: DO NOT BUY THEIR PRODUCTS!!
