Product Review: Nalgene Grip-N-Gulp Sippy Cup

Picture this: You've just found your toddler's sippy cup on the floor in the middle of a puddle. Did juice fall from the sky? Did milk miraculously come from your carpet? No. The sippy cup valve got knocked out, or the seal wasn't tight enough, or maybe the cup always leaked to begin with. Sound familiar? Then you have GOT to get a Nalgene Grip-N-Gulp sippy cup!! These things are AMAZING. They do not leak. Ever. Period. End of Story. And the valve is impossible to knock out. As always, it's BPA free, and did I mention it doesn't leak ever? While a little on the pricier side, these will last through all your kids, and you won't have to replace your carpet because of the leaks! I'd say you save money in the end, if not your sanity as well!
