Great, sturdy, easy to clean toddler cup

AlexxAugust 4, 2025

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. Read more

Great buy!

Fantastic and very durable. To stop leaking, you need to be sure the top is snapped shut. Comfortable to carry and easy to use. Nice design. Read more

Best metal straw cups

ravenJuly 26, 2025

These are the absolute best stainless steel bottles available for toddler/preschoolers. My daughter is 18 months and has been using one since 13-14 months for water. She was using plastic straw cups for milk, but I finally bit the bullet and got another one of these for milk. My 4 year old loves her plastic Frozen bottle, but I’m replacing it with one of these as well! They clean so easily. They don’t stink. A little heavy for a small baby, but by the time they get into toddler age it’s the perfect size. My daughter can also easily open and close it herself as of a month ago. Keeps things cold for hours! Falls and never breaks or gets dented. If the bottle is open, it can leak but it’s minimal. It also depends on how exactly it’s laying, it doesn’t always leak. This doesn’t bother me at all for all the other benefits! Read more

**THERMOS FUNTAINER Water Bottle with Straw (12 Ounce, Teal) Review**

Jason F.September 14, 2024

Here’s my detailed review of the THERMOS FUNTAINER Water Bottle after thoroughly testing it with my kids. **Pros:** 1. **Insulation Performance:** The stainless steel vacuum insulation keeps drinks cold for hours. My kids' water stays refreshingly cool even on hot days, making it perfect for school and outdoor activities. 2. **Durable Build:** The stainless steel construction is robust and can withstand drops and rough handling. A real plus for active children. 3. **Easy to Use:** The push-button lid makes it easy for kids to open and close the bottle on their own. The pop-up straw is a hit, making drinking fun and spill-free. 4. **Hygienic & Safe:** The integrated carry handle and covered straw keep the drinking area clean and free from dirt. Plus, it's BPA-free, ensuring safe use for kids. 5. **Compact Size:** The 12-ounce capacity is perfect for little hands, fitting nicely into lunchboxes and backpacks without adding too much weight. 6. **Appealing Design:** The teal color is vibrant and appealing. My kids love the look, making it more likely they'll stay hydrated. 7. **Easy to Clean:** It’s dishwasher safe (top rack), making cleanup a breeze for busy parents. The wide opening is also convenient for manual washing. **Cons:** 1. **Non-Leakproof Lid:** Although generally reliable, the lid can occasionally leak if not closed properly. It's important to ensure it’s tightly secured. 2. **Straw Cleaning:** The straw mechanism requires thorough cleaning to prevent any mold build-up. Regular maintenance is necessary to keep it sanitary. The THERMOS FUNTAINER Water Bottle with Straw is an excellent choice for kids. Its insulation, durability, appealing design, and ease of use make it a standout product. Despite minor issues like occasional leaking and the need for careful straw cleaning, its benefits far outweigh the cons. A great investment for parents looking to keep their kids hydrated in style!

Mostly good, small leak issue

Matthew ThomsenSeptember 24, 2025

These are a great size for my 1.5 year old, and they keep water cold. I took off a star because they sometimes leak into the lid a bit, so when you open them water pours out. They still work well and my daughter loved putting her own stickers on! We have 2 and use them every day, the leak issue is pretty minor. Read more

Great bottle!

PaulaDecember 7, 2025

I love this bottle for my toddler! She was able to learn to open and close it very easily. It holds the right amount of water for someone her size so it isn’t too heavy even when filled. The best part is that it comes apart and is put back together very simply and makes for easy cleaning! Plus the area part at the top is replaceable so if it get torn after lots of use (or bitten as we know toddlers like to do) I can get a new straw without replacing the whole bottle! Would definitely buy again…although it is so sturdy I may not have to! Read more
