Title: DO NOT BUY!!! KNOCKED OUT MY SON'S TOOTH!!!
Review: If you cherish your child's smile, do NOT buy this product. The hard knob that lowers the straw knocked out my son's tooth. He was walking across the living room, sippy cup in mouth, and tripped over his shoes. The knob of the sippy cup completely knocked out his tooth, root and crown and all. Think about how clumsy toddlers are. This is NOT a safe product for tots and definitely needs to be recalled. I do not even want to give it one star - it's horrible.
