Does anyone have a tip for getting the Measure All Cup to restore it's grip? A customer has asked saying it has lost it's grip so I am assuming that she means the cup portion is loose inside of the measuring part...does any of that make sense to anyone?! I was wondering if maybe she were to put the cup part in really hot water to kinda reshape it...I really don't know as this product is one that just sits in my cabinet (not a big fan of it). Any advise is appreciated.
