I put ice with water from our fridge dispenser in to see how long the ice would last. About 2 hours, but 7 hours later when I dumped the water out to wash the cup; the water was still really cold. So although the ice didn't last super long, the insulation inside kept the water cold. I would definitely recommend for littles! I had an issue getting the lid on with a child in my arms because uou have to find that groove that matches the cup, but my daughter loves this cup! It indeed is spill proof, I tipped it upside down and gave it a shake. The soft straw helps with transitioning from bottle to cup.

This 16oz Hello Kitty insulated mug is perfect back to school. The twist on lid and straw combo is virtually spill proof. This is also great for travel as it fits perfectly in most car cup holders. I highly recommend this for your kiddos or yourself.

This is a much better design and easier to clean than previous iterations from this company. Design is cute and relevant to my child’s current interests. Double wall insulation seems to be up to standards and will keep drinks cold for a long period of time.

These Bluey zap cups two packs are so cute. They are insulated spill proof and they are heavy. They feel like a namebrand isolated cup. The prints are fun. One could be for a girl one could be for boy or both can be for a girl the straws are Handy and they are great for toddlers and older kids.

This cup was perfect for my little guy. The handle is just right for his smaller hands. The design is super cute, or in his words "sooo cool!". There is a different design in each side, which was a hit. For me, I loved the rubberized straw. I worry about metal straws banging into his teeth because he is so rambunctious and always in the go. No worries with this straw, it's safe no matter what. The 16oz design also holds just the right amount of liquid.

This double walled vacuum sealed tumbler is very nice. The one huge drawback is there is not stopper to prevent leakage from the straw if it tips over. The good stuff: the lid screws on and depending on how you start it, it allows for the straw to be on one side or the other so you can see your favorite side when you hold it by the very sturdy handle; the straw components come in two pieces and easily disassemble and reassemble for ease of cleaning, and there is a small hole in the lid to allow for use of straw without problems; the mug is tapered on the bottom to fit most cup holders; it does very well at holding hot or cold temperature drinks for over an hour; it says dishwasher safe but I recommend hand washing as it will maintain the vacuum seal longer.

We recently received the Hello Kitty tumblers and I hey are adorable. They keep the drinks cold for an extended period of time, which is great during this heat wave. Our daughter loves the print, it’s fun and youthful but any one of any age can use them. I would highly recommend. They are reasonably priced.

Since cheer season started this is the go-to cup for my daughter. This keeps the ice hole for hours so she always has something cool to drink. She's gotten so many compliments about how cute it is it's very very sturdy it's been dropped a few times and there's no cracks, dents or chips in it. Everyone is always asking where she got it from. We have only hand washed it so I can't say the durability or anything if you put it in the dishwasher.

The design on the tumbler is very vibrant with the Spiderman and his amazing friends characters. My son loves it and carries it everywhere he goes now. Before we had to remind my son to drink water but now he wants to drink water of his own. I also liked the amount of water it can hold which is perfect for my son. Most of the tumblers that I find either they hold too little that means you have to keep refilling or they hold too much and it becomes very heavy with water and the weight of the tumbler for the little one. It is also very easy to clean. It is very easy to take off screw-on top, clean and rinse and refill. It is also spill proof so no mess to clean up. It is made with very sturdy and durable material so no dents even after being dropped couple of times. It is a good gift idea for a kid. Overall, My son is very happy with this product.

This is a review for a free product. What I really liked: This kept my cold drinks cool overnight! The ice was still frozen! What could be better: it has a very restrictive mouthpiece for the straw. Good for preventing spills but bad for any drinks with crushed ice or smoothies.see pictures. If you remove the mouthpiece, the straw is too short and the lid can’t be used without a straw. I found a taller straw that fin in the opening.
