Playtex has a new "Twist-n'-click" top on these now and they are impossible to use. I really mean impossible. You're supposed to twist the cap on far enough for the little arrow to line up with an indicator for a leak proof fit. First, you can't even screw it on enough to get to that indicator and second, you can't remove the top once it is on!! My husband can't even remove it! I thought maybe it was not screwed on straight, but that is not the case. I can't believe they changed the design of the top (which isn't reflected in the picture of the product here). We have several of these cups with the old style lid and loved them. They never leak, so I don't know why they changed them to this unusable style.
