We've been using the cup every morning and night for 2 years. Granted it might have taken a bit of a harder sook to get milk through the little film initially but that's why they were 'any way up'. The little film eventually perished but by then our daughter was sensible enough not to spill through the remaining wee gap. She still has it in bed now she's 3, with no spills. Wonderful item. Long lasting and am about to buy another for our son's first birthday.
