I hate these bowl . I be go to return they . the lid be super hard to get off and the suction do not work at all ! sometimes I can get the bowl to stick for a matter of seconds , and I can not get they off . then my son reach over and pull they off with no effort at all . if these be wash in the dishwasher and the suction cup be touch anything during the dry cycle , it will become deform and ruin any chance you ever have of it suction . I would not recommend these to anyone .
