I can't even begin to say how bad it is. The instructions say to place the molds into water that has been brought to a boil. That seemed a little warm to me so all I did was microwave some water. Even that caused the mold epoxy to immediately disintegrate and coat everything it came into contact with. I can't imagine how bad it would have been if I had put it into my mouth. A cup from a set I've had for 15 years is ruined as is a spoon I've had for nearly as long. I've tried solvents to clean it and all it has done is smear it around.

I can't say how awful this product is. I deserve more than a refund.
