• "These are the first cups I have purchased that actually don’t leak."
• "Love everything about this cup. It’s so easy to clean and doesn’t leak at all."

Cons:

• "I really wanted to like these cups but I've only had them for a week and my 2 year old already chewed through the leak-proof Straws, so they leak all the time."
• "This product is not leak proof at all."
• "The only thing bad I've noticed is if you don't have the rubber lid ring in exactly the right spot, the bottle can leak."
• "If tipped upside down, with pressure on the straw it will leak out."

• "These cups leak all the time, whether it’s being held upside down or on its side."

Design and Ease of Use

Pros:

• "These cups are a huge hit for my minnie lover."
• "Easy to clean and put together."
• "These cups are cute, I wish they had a little handle, my one year old has a little bit of a hard time holding them to drink."

• "Love the design and love the soft straw for my youngest."

Cons:

• "The straw tends to come out of the lid making it difficult to drink, sometimes impossible."
• "The only thing is my kid got frustrated trying to use these at meals due to messy hands making it all but impossible to hold onto."
• "If your kid leaves water in the middle of the upper straw portion, that will leak out."
• "It’s a little difficult for my baby to hold."
• "The straw doesn’t reach the bottom of the cup, so there’s always a little bit of drink left at the bottom of the cup."
• "It takes so much to suck on the straw to get anything out that she cannot do it yet."
• "The straw slips off too much."
