Review on Spill-Proof Tippee Insulated Sippee Cup - Colorful Water Bottle For Toddlers (9Oz, Pack Of 2) - BPA Free And Perfect For Playtime! by Nicole Stone

I wanted to love these, but after about two days of use one of the bottles started to leak, badly. I opened the cap and saw that the little white plastic thing wasn't sitting quite right, it was very easy to fix, problem was that it kept on happening every few uses. Second bottle started doing the same a few days after. So I would go out with the bottle in my bag and suddenly there would be water dripping from the bottom of my bag. Have to stop using, too bad.
