Everything Sippy Cup

My kid loves this cup.

I have tried a few straw cups and they are not leak proof and will spill out liquid if you press hard to screw on the lid. This straw cup is different and have met or exceeded my expectations. It's not only leak proof, for the most part, the straw can't come out if my toddler pulls on it. It's also multi-functional, though I have not used the suction at the bottom, but it sticks onto the surface pretty tightly. I like this so much that I have referred it to my mommy friends.
