Here's what some of our ZoLi family has to say about their favorite silicone straw cup!

These are the best sippy cups around! Straw is soft, weighted and self suctioning great for babies and toddlers to learn how to drink out of a straw!
We tried every sippy cup on the market for our daughter as we wanted to go straight to the straw from bottle and she was young so it was a big leap. This straw is so soft (which was very nice for little tender mouths, weighted and it sort of helps suction the liquid so it helped her learn how to drink with a straw very easily. The weighted bottom is nice so it always goes to the liquid and she didn't have to figure out how to tilt the cup to get her drink. The handles are great so she could hold the cup herself too. One tip is we always use a strap so she can't throw it and it's always in reach. Since it does sort of suction the drink up the straw we are careful to loosen the lid a bit when not being used to drink so it doesn't make a mess. All around a fantastic sippy cup we would highly recommend!
