"The media could not be loaded. At first I was really excited for this product because I’ve heard many good reviews about it and I’ve recently purchased a zojirushi rice cooker and it has worked perfectly. When I received the product, I immediately went to wash it with soap and water, just as I was shaking the bottle I found out that the bottle was leaking NON-STOP, I’m assuming this is just a defected product, so I will be returning it...."
