The only cup we use

We have gotten a few of these cups for my daughter, they are the only ones we regularly use. There are a few flaws, it will leak if you put cold drinks in it. As the drink cools it comes out the top a little bit. We have also counter threaded one and ruined it. But it can be thrown and dropped and hit with a 3lb sledge and not break or leak. Also she can drink at any angle.

At first, I thought this cup was amazingly innovative. The weighted straw allows my son to drink at any angle at all, which is great. The only problem is that the cup leaks. The click lock does not always work, and it would take a fairly older baby to be able to put down the straw alone. If you constantly keep an eye on this cup, it's amazing, but for babies that throw and play with cups- you're looking at some leaks.

I loved these cups initially and thought they were innovative and brilliant. My son and niece still use them, and love them however, the liquid in the cup backs up in the straw if the cup is put down. It makes a puddle of whatever liquid is in the cup and will continue until there is no liquid left in the cup. You can stop the spill if you crack the click lock seal. But remember to lock the cup again before your LO picks it back up. :)
