Tommee Tippee 2 Pack 9 Ounce Insulated Straw Cup (Explora Easiflow Truly Spill Proof - Purple & Pink)

These really are spill-proof and leak/drip-proof whether open or closed, and that's why we bought more after losing the straw to the one we had before.They also do not sweat, so that's another path to avoiding a wet mess and water rings on your table.Some might think assembly is tricky, but it's not a problem.Compared to the Camelbak adult and children's bottle (Eddy), these require more effort to suck up the liquid, so if your child is used to that kind of flow or if you were trying to maximize hydration, they might not prefer these, but our child uses all three types without issue.Seriously, these do not leak!

Too many pieces to clean and gets stinky fast even with just water in it. If you don't get it together just right, it can be hard to get any liquid through. I always have to try it out and adjust the parts before giving it to my daughter. My daughter loves them, otherwise I'd give a 1 star review.

Unfortunately, it worked well for 2 days. The baby has suck the straw extremely hard to get something out of the bottle.

I absolutely love these cups. I bought mine 3 years ago and they still work great. Yes, there are a few pieces you have to clean and you do have to put it together PROPERLY in order for it to work, but it is the only cup we will use for milk!
