My son is tough on his cups, as most busy toddlers are. We go through so many cups a year due to the seals failing, the straws falling apart or being dropped and the cup cracking. These cups are so heavy duty, I don’t see them failing us anytime soon! I love that they are double walled for insulation during the summer months to keep your drink cold. The straws are much thicker than the competitors, making them less likely to leak with minor chewing.

I’ve received the Zak Designs 12-oz. Stainless Steel Double-Wall Tumbler for Kids with Antimicrobial Straw, 2-Piece Set two weeks ago. I couldn’t be more happy with the product. It’s winter, it’s come at perfect time. I recommend this product to all my friends and family.

These cups are amazing! They keep liquid cold and ice for hours...they are not 100% leak proof, if the straw is not closed they will leak. BUT they are much better then most we have tried and I would still recommend them. My 15 month old LOVES it because it looks like a small version of my cup and he loves to drink from a straw.

Too heavy for little hands Topple over easily But what was really frustrating is that these cups spill more than the other toddler cups. Supposedly this brand was “no spill,” but when I accidentally knocked over a cup water seeped through a sweater that was nearby so quickly. No way am I going to give my little ones to take to school and then their backpacks will get wet.

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!!

These are the absolute best tumblers that I have come across for small children. The design is beautiful, pretty colors and very appealing to my granddaughters. The tumblers are made of great quality materials, with a soft straw for little mouths and sized perfectly for little hands. They are quite easy to clean and dishwasher safe. Tumblers are also vacuum insulated which keeps drinks cool. Great product. I would definitely recommend.

My kids love these cups! They don’t feel like a sippy cup so it makes them feel more grown up. I’m always carrying a cup that has a straw and they feel like big kids carrying their cups with straws. I can take a big sigh of relief because I know that we won’t be spilling water everywhere! Designs are adorable. Highly recommend!

These cups are cute and funtional! You can fill it with water, hold it upside down with no leaks even with the straw in. My two-year-old granddaughter loves that the cup is just her size. I like the silicone straw because its SUPER durable! At preschool, the cup gets tossed around a bit and it no worse for the wear. The Little Princess print is adorable! It is very easy to clean and not stained by juices. I have no complaints.

The cups are durable, easy to clean, and my kids like them. They aren’t completely leak proof but better than most cups I have used. My one year old, four year old, and five you old def put the durability to the test. They do keep things cold for several hours.

My granddaughter was delighted with these, they hold enough of her favorite drinks and they are kept cool for a decent amount of time. She loves the princess displayed on the outside of the cups and best of all they are spill proof. Would highly recommend.
