I love this product and my baby does too! The cup is leak proof and very durable. I love that the weighted straw prevents my baby from sucking air. We lost the cup and went out to buy a new one right away! I love all of the bright colours it comes in and It is very reasonably priced.

My daughter loves this cup and so do I. I first got it because with other straw cups she wasn't able to drink right to the bottom and would just suck in air when the liquid got low, which made her gas issues worse. With this cup she drinks every last drop. The only time it leaks is if there is a bit of water left in the straw above the valve, but that's only a couple drops. It does come up the straw and leak with milk, but I have never seen a leak-proof straw sippy that doesn't do that. It also seems quite durable and is withstanding all the times it's been thrown off the highchair onto our hardwood floors. It's also not so hard that it dents the floors easily. Would definitely recommend this cup!
