Bests & Worsts Reviews from Amazon

I have tried dozens of different sippy, straw and trainer cups and this is the worst one so far. My 18 month old got VERY frustrated with this cup. I tried it myself as well, and unless you really press your nose into the plate in the center of the cup, the flow is very minimal. Not only that, but I think it actually hinders the transition to a normal cup, because one of the biggest hurdles is knowing how far back to tip the cup. With this cup, you can tip it upside down, but unless you press the plate, nothing is coming out. Also, like other avent sippies, the valve is multiple pieces that should really be taken apart at each use and washed unless you want mold growing in there - even with just water. They say not to use this cup with juice either, and I think milk would really get in the nooks and crannies as well. So at least its leakproof then, right? Sort of. It's true that it doesn't leak if the plate isn't pressed, but it doesn't take much to press the plate a little and allow a slow dribble. For that reason I wouldn't use it as an accident-proof cup for in the car or other unsupervised use anyway. A straw cup works much better for that purpose. If you're restricting to water anyway, spend a couple weeks transitioning to a regular cup and save yourself the hassle of another unnecessary "transitional" stage. Sure, there will be some spills, but it will be over faster, and you can use a straw cup (which would still have adult applications later) for the times you need something less messy.
