Seriously!! We have 3 Zoli cups, all leak. I bought a B.Box after a Bee said it didn't leak. But the water comes out the top when just sitting on the counter. Then it leaked all in her day care bag, all closed up. We just got the OXO Tot Straw Cup, so still testing it out. But another bee said it leaks too.
Seriously!! Why is this so hard to find a cup that doesn't leak???
