    • Great bottle
Color: Construction Size: 12 Ounces
Bought this for my son and it’s held up great so far. Keeps water cold for hours, even after being in his backpack all day. The straw is easy for him to use on his own, no leaking that we’ve noticed. Size is perfect for school and it’s easy to clean. Good quality for the price would buy again.

    • Great, sturdy, easy to clean toddler cup
Color: Butterfly Frenzy Size: 12 Ounces
I researched metal toddler cups forever before deciding on this one and I’m so happy I went with Thermos. We have 2 of these cups for my 2-year-old and they’re great. They are super sturdy (my daughter has quite the arm and throws her cups daily from up in her high chair). They leak if they’re laying on their side with the top open, but that’s kind of to be expected. We just make sure to keep the top shut when my daughter isn’t drinking from it. It’s very easy to open and my daughter does it herself no problem. The little handle is perfect for toddlers to carry it themselves. They keep water cold for a long time; I find ice stays frozen in there for a while. They’re easy to take apart and clean. I like that the straw is clear so you can see if there’s anything in it. You can also buy replacement parts for the straw sections of the cup which is great. They’re dishwasher safe and fit in a standard car seat cup holder (all these were an absolute must for a toddler cup for our house). We have this butterfly one and the strawberry one. Neither have chipped or faded yet and they’re washed and dishwashed regularly. One goes to daycare with my daughter and has held up very well. Overall extremely happy with these cups and highly recommend for a toddler. ... show more

    • Leakproof and easy to clean!
Color: Construction Size: 12 Ounces
I got this water bottle for my 1 year old grandson whose father works in the construction industry. I take care of my grandson in the mornings while his parents work. This water bottle is exactly what I needed. It's small enough to fit in my lunch tote/purse so I can always have his water bottle on hand to keep him hydrated. I love that this water bottle is leakproof. The last water bottle I tried for my grandson leaked all over my front passenger seat. With this water bottle, I can carry it in my purse and not worry about leaked water ruining the items in my purse. I also like the straw, which makes it easy for my grandson to drink. I would say that the angle of the straw is a bit low and so I do make a point of being careful to not accidentally hitting my grandson's chin with the bottle when I am offering him a drink from the bottle. Unlike some other water bottles with a straw that are hard to clean, the way the straw is implemented in this Funtainer water bottle makes it easy to clean. And it's dishwasher safe! As a one year old, my grandson loves to throw things to the ground. I've had other Thermos water bottles for myself with a plastic lid that would break should I accidentally drop the water bottle. This Funtainer water bottle's lid seems to be better quality as it has survived being thrown to floor from the high chair and to the asphalt from the car seat. Although the cap and straw are made of plastic, I was willing to pay more for the fact that the bottle itself is stainless steel. I do try to avoid using plastic as much as reasonable. I love this water bottle for my grandson so much, I am getting him another one. I am thinking he can use these water bottles for years to come! ... show more

    • My son is obsessed
Color: Construction Size: 12 Ounces
We have had this for a little while now. I wanted to wait to write a review after my toddler had some time to really put it through the wringer. Aside from the great design that my son loves, it has held up really well. It still looks brand new. What I really loved about this is that it does not leak. I have had trouble with many of the "leak proof" cups I was getting him, in fact leaking. although there was one time, I thought the thermos was leaking it was my fault for not properly inserting the straw, so user error was the culprit. It keeps drinks cold for a long time and is easy to clean. I would say it's definitely worth the price. ... show more

Such a great water bottle for small kids! I got this for my one year old daughter! I love how the straw is soft and she has no troubles drinking liquid from it. It is a pretty pink color. So easy to wash! The straw easily comes out and you are able to wash the lid and all the small areas. It’s a little pricy but so worth it. I got the same one for my son when he was 1 and he is now going to be 4 and still uses and loves his! ... show more

    • Water spills
Color: Navy Size: 12 Ounces
I was looking for a replacement water bottle for my 7-year-old. We had Hydro Flask before until he lost it. As I was browsing through different water bottles on Amazon, I noticed there are 3 different types of straws for water bottles - hard straw (like what Hydro Flask has), silicon, single-cut straw (Cambelbak uses this kind), and standard silicon straw (this is what this Thermos Funtainer uses). I am going to give you the pros and cons of each straw type. Hard Straw: Pros It's easy to clean and seals well. I didn't experience any water skills with our previous Hydro Flask. Cons This may not be a con for most people, but if you like the soft texture of a silicon straw, then you wouldn't enjoy this type of straw. Silicon, Single-Cut Opening Straw Pros It seals water pretty well, and we occasionally experience a water spill with this type of straw, but it is no big deal. Unlike the hard straw, the texture of silicon won't leave you feeling like you're biting a chunk of hard plastic whenever you drink from the bottle. Cons Because the opening is a single cut in the middle of the top end of the straw, the spout will wear out over time, and you will need to purchase a replacement. The design of the spout might be slightly difficult to clean. Standard Silicon Straw (what this water bottle uses) Pros Again, the soft texture enhances the user experience. Cons Combining a standard silicon straw and a spring-operated single-hand opening results in a water skill, should you fill water all the way up to the bottle. The opening button is cleverly designed to be sensitive (perfect for the target customers - mainly kids), but if you have a water bottle, the water will leak from the straw. We had an incident where we put the filled Thermos Funtainer in a bag together with my son's homework, and we discovered the homework was damaged by water. When I investigated further, I found this water bottle to be the cult. Overall, this is still a great water bottle. We like the quality of the brand. However, you want to consider a couple of things before making the purchase. 1. Cleaning: the straw of this bottle comes in 2 small parts. You will need a small straw-cleaning pipe to do the cleaning. 2. Size: I doubt you can fill up 12 oz of water for this water bottle, so if you're buying it for a younger toddler, this is perfect. Consider purchasing one size up for older children. ... show more

    • Made to last and easy to Clean
Color: Navy Size: 12 Ounces
This kids’ thermos bottle has easily lasted through years of daily use in our house. Easy for kids to carry around and perfect size. The stainless steel design keeps drinks cold for hours, and I really appreciate that every part comes apart for deep cleaning — no hidden spots or trapped moisture. It also fits in the graco cup holder while travelling. The best part is being able to buy replacement straws separately instead of replacing the whole bottle, which makes it feel like a bottle that can truly last throughout childhood. Durable, practical, and still one of the best kid water bottles we’ve tried. ... show more

    • Perfect for toddlers
Color: Mint Ombre Size: 12 Ounces
These are my favorite! Stainless steel but more lightweight. Cute prints and a handle which makes it easier for my toddler to use. It’s only leak proof when the top is shut, but we prefer that. Great cup!
