Munchkin® Any Angle™ Weighted Toddler Straw Cup with Click Lock™ Lid, 10 oz, Green, Unisex

The closing feature makes it very convenient for traveling and on the go. The weight is great because my toddler can drink every last bit of the drink without getting air.

[This review was collected as part of a promotion.] I've gone through what feels like a dozen "leak-proof" cups, but this b.box Sippy Cup is the first one to actually survive my daughter's "gravity tests." What I Love: The Weighted Straw: This is the real game-changer. Whether she's reclining on the sofa or tilting the cup upside down to see the bottom, the straw moves with the liquid. No more frustrated screams because she's sucking air! Truly Leak-Proof: I can toss this in my diaper bag without fear. Even when she drops it from her high chair (which is often), it doesn't leave a puddle. Easy Grip: The handles are perfectly sized for tiny hands. It really helped her transition from a bottle to a cup with zero fuss. A Quick Tip: Make sure you get the little cleaning brush set for the straw! Since the straw is a bit narrow to ensure it stays spill-proof, the specialized brush makes cleaning a 10-second task instead of a struggle. Bottom Line: If you're tired of cleaning up juice puddles or hearing your kid get upset when their drink "disappears" because they held the cup wrong, just buy this. It's worth every penny for the peace of mind.
