During this days I try the wisoap and follow the instructions but this thing didn't work. I charger for 3 hours and put water and detergent in a plastic container then I put a blouse and the wisoap. I just keep hearing a weird sound and the wisoap turn a blue light and nothing more. I left there for about 40 minutes and the wisoap just keep doing the same. At the end I have to handwash my blouse cause the wisoap didn't do anything. Don't waste your money and don't write to the customer service cause they just want a photo to see if the wisoap work. Could you believe that? I'm going to return it cause I want my money back. No I don't recommend this wisoap to anyone.
