Good quality. Does not leak even with hot water.

We have about eight of these Kiddie bottles and they are used daily for kids ranging from one to six years old. Each water bottle has held up to daily use, never leaking and never wearing out. Sure, the tops have a little wear from kids who like to chew on the spout but nothing that makes the bottles unusable. We wash these nightly in the dishwasher by removing the inserts from the tops and putting those in the silverware basket. The tops and bottle are then washed on the top drawer of the dishwasher. The water bottles have held up perfectly to years of this daily use and dishwashing. These are perfect for kids and I highly recommend it.

I bought another for my 4-year-old's playmate next door. Twinning colors!

I love these bottles. The kid knocks them over and no spills. The only time there's any leakage is if she holds them upside down for a bit of time. Other than that, no liquids to clean up. They are also very easy to clean with no worry about mold ever-growing anywhere. I've experienced some bottles for kids with parts that are sealed that mold ends up growing in. There are no sealed parts with these bottles and the plug that prevents spills can be removed for cleaning (or for good when the kid is big enough to stop knocking over her bottle).

These have got to be some of the most durable kid's water bottles made! They definitely last way longer than traditional sippy cups, and they hold a lot of water for a little one. They stay in car seat cup holders pretty well, and the loop on the lid makes them easy for kids to tote around by themselves. We were given one as a gift when our daughter was pretty small, and because we liked it so much, we never tried another type or brand.

Easy to use. My 4-year-old asks for the valve out so he can drink more quickly, but it's not a hassle.

Great water bottle for babies and young children. Nice size for them to hold.

This cup really works as it truly is non-spill, my daughter wishes she had bought these for her children years ago and saved her money from buying all the others that claim to be non-drip but never live up to expectations. Definitely worth the money.

Simple non-leaking bottle for our 3-year-old boy, the amount of abuse he gives these bottles. While all the other brands lasted about a week! This one is long-lasting!

Great bottle. I bought it as a gift for my students!
