Title: Worked for about a month now LEAKS EVERYWHERE!
Review: I have like 6 of these cups because they were one of the only cups my son would use. THEY SUCK! They leak everywhere out of the side! it is like a constant drip and when monkey bangs them then the valve comes loose and we have an even bigger mess. Very disappointing. Hope I can find a great cup.
