The 18oz kids water bottle is well-received, with customers praising its size, color options, and ability to keep drinks cold. Many parents report their kids love the bottle and it encourages them to drink more water. However, some customers have experienced issues with leaking, rusting, and defective bottle boots.

Straw doesn’t stay in place

[This review was collected as part of a promotion.] The straw on the lid does not stay in place. It moves while you are drinking, and then liquid does not come out.

Dented with first drop

[This review was collected as part of a promotion.] I’ve tried lots of different brands of insulated cups and I’m sad to say this one was dented after just 1 day when my baby knocked the cup over. I’m pretty tough on my tumblers of other brands and none of them have dented so easy.

Lots to like but one major flaw

[This review was collected as part of a promotion.] Love the size of this cup and typical HF quality. It's the perfect size because it is one of the few insulated cups that fits in our daughters two different car seat cup holders. Great that you can clean the entire thing thoroughly. Biggest downside - the straw configuration! In theory - it's great because it's easy to clean everything. The downside, when our 2-yr-old daughter is walking around or pulling it out of her carseat cupholder, she'll often grab it by the straw and the whole straw setup pulls out of the lid and the cup falls and spills everywhere. 5 stars for size/quality 2 stars for straw issue - what happened in R&D for a kids cup?!

Lid color

[This review was collected as part of a promotion.] Why would you put a pink lid on the red bottle? Boys don’t want a pink lid! Why can’t you have the lid color match the color of the bottle?

Kids

[This review was collected as part of a promotion.] They are super cute but they leak! Having kids you can’t have them leak.

100% No Leaks

[This review was collected as part of a promotion.] This water bottle is amazing. Seriously doesn’t leak. Easy to clean and assemble. We don’t put ours in the dishwasher so that’s a huge time saver for us to easily break down and assemble. The kiddos take their bottles everywhere. We are really happy with our purchase.
