Title: Great idea, but leaks
Product review: I have tried BornFree, Sigg, and Klean Kanteen. Klean Kanteen tastes the worst, and leaks everywhere. I've resorted to using it only for water, and still, my daughter is soaked regularly with this sippy. I understand that the problem is with the Avent valve system and not the cup itself, but for a toddler, this cup is unfortunately not the answer. Please note: it's not that she's dumping it upside down or banging it around; it simply leaks when she drinks out of it, and runs down the side.
Would you say this review depicts the product in a flattering or unflattering light?
