Review on Munchkin Any Angle Weighted Straw Trainer Cup With Click Lock Lid, 7 Ounce, Pink by Malacia Hernandez

I bought this cup for my daughter when she began her transition away from a bottle around 11 months. There are some things to note about this cup so that it functions properly.First, the straw was really hard to suck through when I first tested it. However, YOU HAVE TO MAKE SURE THE DISPOSABLE PLASTIC COVER IS REMOVE FROM THE WEIGHT AT THE END OF THE STRAW BEFORE FIRST USE. Also, it helps if you roll the top of the straw where the valve is through your fingers a couple times to initially open the valve before first use. This is also suggested in the instructions that come with the cup and I think some people who left bad reviews about the slow flow of the straw may have not done one or both of these things. I myself did not do either before trying the cup the first time and I also thought it was impossible to pull through.Second, THIS CUP DOES LEAK A SMALL AMOUNT. The valve that keeps the milk from coming up from the straw is about an inch and half below the top. This means that any milk that is in the straw above this valve will leak when the cup is tipped over, thrown, or if the straw is flicked such as when you open the cup after closing it with milk in the straw. THERE IS AN EASY FIX FOR THIS. After your child is done drinking and before the cup is thrown or closed roll the top of the straw through your fingers, so that the milk above the valve can go back down. OTHER THAN THIS I HAVE NOT HAD ANY LEAKS WHEN THE CUP IS PROPERLY CLOSED.Third, I ended up ordering 4 of these cups for my daughter to use daily for the milk we send with her meals to daycare. Somehow, I received cups from two different batches or from two different manufacturers and the tops of two do not fit the other two and vice versa. This led to the cups significantly leaking from around the rim and I thought at first, they had warped in the dishwasher. IF YOUR CUPS ARE LEAKING AROUND THE RIM, PLEASE CHECK THE PRODUCT NUMBER ON THE LID AND CUP TO SEE IF THEY MATCH EACH OTHER. Apparently, Munchkin uses more than one manufacturer, and the products are not exactly identical. This is a little annoying, but I can live with it because overall the cups work really great for my daughter. The weights straw works great, and she has even leaned all the way upside down and still been able to drink. The straw is awesome verses a sippy cup because it is actually helping to strengthen the muscles, she will use later for talking. And the handles on the side allowed her to immediately be able to drink independently without any trouble at age 11 months.OVERALL, THIS PRODUCT IS GREAT. I HAVEN'T FOUND ANYTHING BETTER SO FAR!
