So far, so good!

Great cup for our 3 1/2 year old. Doesn't leak and we've dropped them a few times and the lids or cup haven't broke.

LEAKS EVERYWHERE

I would give zero stars if I could. These cups are horrible. They literally POUR out water if they’re dropped, thrown, etc from around the base of the straw as well as the straw itself. They’re only leak proof when the straw is put away with the sliding mechanism. I don’t know who in the world designed these cups but they should go back to the drawing board.

False claim “spill free” IT DOES Spill

False advertising - I purchased these two cups for my toddler mainly because the box, and cups were labeled as “spill proof” which is a misleading claim and completely incorrect. By the time I got home and realized that whether I put juice or water the cups leaks. There is a gap between the straw opening and the actual straw size that is due to design rather than defect. Please! PLEASE do not purchase and waste your money there are a lot of products out there who actually serve the purpose. I also contracted the company to file a customer complaint and sent my receipt and everything after an extensive questionnaire they said they are sending replacement “lids” and only for one of the cups but I purchased 2 in the pack I purchased not to mention they WILL not send you the matching color. I wish I could have returned it to the manufacturer not the store, however they do not let you send it back to them. They claim bc you purchased it from Sam’s. As a consumer it doesn’t matter where you get it from, there is a design issue not a retailer issue.
