Great, sturdy, easy to clean toddler cup
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.

LOVE it
Great quality. This is our 2nd Thermos funtainer and out of the many other types we have this one is long lasting, easy to clean and I love that it is stainless steel. It's also not super heavy like the Yeti is. The print is also so fun and cute.

Best metal straw cups
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!

Water stays cold 24 hours ice stays whole for 12 hours
I’ve wasted money on generic supposedly stainless steel insulated water bottles for kids for my granddaughters and they do not keep their water cold. I did my research. Funtastic kids by Thermos brand have high reviews and met all my expectations. They are 12 ounces, my granddaughter can get her hand around them, the lid has a handle for her, they are easy to push open and snap shut. MOST IMPORTANTLY, they are stainless steel, insulated, not heavy, come in kids designs. THE WATER STAYS COLD FOR UP TO 24 HOURS AND ICE DOES NOT MELT FOR UP TO 12 HOURS ! This is plenty of time for my granddaughter to take to kindergarten for an eight hour day and to sports or daycare after. Why waste your money on other brands that don’t work?

Finally found the perfect water bottle
Perfect size for a toddler, doesn’t leak, cute, easy for her to carry, and well insulated. Love this bottle. I bought two I switch out daily. They are easy to take apart and clean.

Perfect toddler cup, fits in the car seat cup holder, inconsistent lids though
I bought the "Purple Hearts" design first and loved it so much I got the "Butterfly Frenzy" about a month and a half later. This is the only cup with a lid out of probably ten toddler cups we have that actually fits in our Graco car seat cup holder. It quickly became my two-year-old's favorite. She can open and close the lid on her own and the straw is easy for her to drink from. The designs are adorable and the colors stay bright without fading, even with hand washing. Cleaning is easy because the lid and straw come apart. It's also really durable. My daughter has dropped them a bunch of times and they haven't cracked or broken. The insulation seems to work well, but I haven't tested it much outside. My only complaint is with the "Butterfly Frenzy" cup. The lid it came with is clear instead of the opaque one shown in the listing and on the "Purple Hearts" cup. If I didn't already have the first one I wouldn't care, but it's a little annoying that they don't match. That said, it doesn't change how well the cup works and my toddler doesn't care if her cups match, so I'm still happy with it.

Doesn't leak, long lasting
We love this water bottle. My daughter takes it to preschool every day and it has held up perfectly. It doesn’t leak at all and keeps her water cold for a long time. She loves using it, and as a parent, I really appreciate the quality and durability. Very happy with this purchase — highly recommended!

The items didnt come in a box. Just thin plastic bag only. We are lucky that the bottle came in good shape. The print on the bottle looks weird. As seen in the photos, i thought it is moldy. If i had to pay full price, i would have returned to get refund. Good thing is the bottle is light. The parts are easy to be taken out to wash and put back.
