it works nice. I put the cake of my brother and my cake in a lasagna bowl. Bought for 2 euro a dishwater-box(how do you call those plastic things) at the blokker. Filled it up with water put the aquarum heater in it and covered it with a towel. I've put it in a commode but it was getting wet in the inside so I opened the door a little to let the waterdamp come out. It works nice.
