I've bought 2 different sets of this brand and both times one leaks. It leaks out the side of the lid.

These cups are great. Unfortunately after only a week, one of my valves is leaking and the cups/ characters are already scratched.

We have had these a month or so and the started out fine until they didn’t. The now leak no matter what we do. It is quite frustrating and we are about to just throw em out. Waste of money.

They leak! Which is number one criteria for a toddler cup. They leak from the seal ring when tipped over for drinking. It's so annoying. 2 stars only because they are adorable and sturdy. But leaky

My 2yr old Grandson cup straw is broke…I took cup away from him because I was afraid he might bite the rest of the straw off and swallow it… Will not buy again…

[This review was collected as part of a promotion.] Our 8-year-old loves Spiderman, and we thought these cups would be a hit and a good replacement for the old "sippy cups". As it turns out, they were even better than expected. The cups are well made and leak-proof, with bright colors and fun designs. They are also very easy to clean, with wide openings and easily removable parts. The unexpected bonus was that these cups also work very well for my 89-year-old father-in-law. Unfortunately, he is bed-ridden and has a difficult time using a regular cup due to arm tremors. These cups work perfectly for him, allowing him to sip easily and not spill a drop. They also seem to keep drinks cooler for longer than other cups. All-in-all, a win for all generations!

I bought these from Sam's after using other zak water bottles just like the purchased from other stores. These were bottles are completely faulty and leak from the lid even when it is completely screwed on. Terrible waste of money and it damaged my wood floors where it leaked.

[This review was collected as part of a promotion.] I got these cute cups because they had Yoda on them with a straw. My 6 year old grandson always wanted to take his drink with him in the bedroom so he could play his games. I dreaded hearing "can I have a paper towel " because I knew that meant he had spilled something. Since I got these two tumblers I don't have to worry about the spills, or leaks, and keeping the 12 Oz. cold or hot. We are both happy !

Tight locking Lance was good study quality keeps my kids happy! These cute little Disney cups are now a must have for our family when we hit the car. Tight locking Lance was good study quality keeps my kids happy! The thermal lining in them keeps cold things cold and hot things hot which is ideal when you have a toddler in the backseat. I would highly recommend this product for anybody who has a littles in the car that are constantly taking lids and stuff off.

I bought 2 packs of these right before Christmas for my Grandkids It is now just Feb and my daughter said that the pieces inside the top of the straw are deteriorating and have almost completely came out so they are leaking.I paid 16.98 for these and they should have lasted much longer than this.But in checking the website it says warranty does not include the straw which is crazy it is part of the cup.Very unhappy Grandmother
