I got these for my 4 year old and thought he might be a little too old for them, but have found them to be the perfect water bottle to use around the house because they are spill proof. He loves the straw and it has a mechanism that prevents it from leaking if it tips over. The Spidey and Amazing Friends theme was the perfect choice and this is now his go to choice of cup. He can even easily screw on the lid by himself.

So my daughter absolutely loves the Bluey cups and insists on us using only them! She struggles a bit with using the full straw attachment so it gets minus a star for just that otherwise it’d be a solid 5 stars! I love how easy it is to clean and how they don’t hold onto odors! Really good at being leakproof and only had a few leaks randomly here and there but for the most part it’s very good at being leakproof!!

My son uses different "spill-proof cups", but many still leak or spills if he accidentally knocks them over. However, this Zak 12 oz. Tumbler has proven to be a true Leak-Proof Cup. I chose this particular cup because I really loved the cute design & bright colors, but I also wanted a insulated cup that could keep his drinks cold no matter the season. This cup does a wonderful job at that! My son really likes the straw top and it's easy for him to drink from. I haven't had any issues with the cup leaking and it's very simple to clean and fill with liquids. Out of all the cups we've tried, this has definitely been a favorite and I plan on getting a more.

The features on this product are great! They are definitely no spill and we are happy about the anti microbial feature. They are sturdy and keep drinks both hot and cold. They also fit the cup holders in the vehicle perfectly. My granddaughters were not very enthusiastic about the Star Wars theme we received, but they both are happy to have them now. It was a bonus that each one had a different design. I would definitely purchase another set for them with more of a “girlie” theme if possible.

My grandson loves these cups. He just turned four. I have not had any leakage when dropped, and it keeps the cold drinks cold. He sucks them like a straw. I hand wash, and use a bottle brush to clean the straw part. It says the top part is dishwasher safe, but I clean the detached straw, and straw opening on the lid with a bottle brush. You could use the dishwasher for sanitizing.

These lil cups are great! The cups are thick enough to hold temperature and they are definitely spill proof! They have a great straw design that I think will be easy to keep clean and the characters on the them are cute and fun for my daughter. They are just a bit tough to get the drink out, but my 3 yr old can do it. They are also just a tad wide for lil hands, but she just uses both hands when it is full and heavier. Over all a great cup!

My grandkids, ages 2 and 3, loved these cups! they are just the right size for small hands to hold, and are leak proof. I also like the fact that they are stainless steel lined, so cleaning is easy and they don't stain. They keep drinks cold for a long time as well.

This Zak Minnie Mouse spill-proof water bottle is an absolute winner! We got it for our 4 and 6 year olds and it has quickly become their favorite. First off, the Minnie Mouse design is just adorable. The bright colors and cute details are a huge hit and make drinking water fun. More importantly, it truly lives up to its "spill-proof" claim! We've had our fair share of leaky sippy cups and water bottles, but this one has been fantastic. Even with enthusiastic tipping and shaking, we haven't had any major spills. This is a lifesaver for car rides and outings. The size is perfect for little hands to hold, and the flip-top straw is easy for them to use independently. It also seems very durable and has held up well to being dropped (which, let's be honest, is inevitable with kids!). Cleaning is also a breeze. The straw and lid are easy to disassemble and wash thoroughly. As a parent, convenience is key, and this water bottle delivers. If you have a little Minnie fan and are tired of messy spills, I highly recommend the Zak Minnie Mouse spill-proof water bottle. It's cute, functional, and a great value. Five stars all the way!

The lid and straw are dishwasher safe on top rack. The pictures on the cup itself wear off with each run of the dishwasher so I would recommend hand washing only. We have four young kids and these go everywhere with us (car, park, zoo, museums...). If the lids are tight it's hard to drink water out of them, but if you loosen the lid they leak. Our oldest is 5.5 and he does better so these are probably good for older kiddos.

Truly love the Zak cups especially the metal ones! These are actually leak proof and better yet, they come as a 2 pack! I love the flexible straw so if my toddler runs with it he won’t get hurt like other cups. The designs are so cute! These are the perfect milk cups for us and use them daily!
