Review: Worth it! - Holds 32oz which is enough for my kids to get through the day at school. It keeps liquids cold all day, their drinks are sometimes still cold when I change them the next day! They're simple in style, which is great for kids with stickers. The three different lid types is also a bonus. Lastly, they're very durable! Im buying my second set because the ones we bought last year made it through the whole year!
Review: SURVIVED SPACE MOUNTAIN - Hands-down, this is one of the best water bottles I’ve ever had! This keeps my water cold for hours. I absolutely love the small chug top. It has the perfect water flow amount and it securely seals so no water leaks in my bag. I had this tied to the side of my backpack in the water bottle pouch, while I was in Disney. I went on Space Mountain and on one of the bumps, it came out of the pocket and slammed against the track. Luckily I had it tethered to the backpack or it would have been a goner. As you can see, it is quite dented, BUT IT STILL WORKS! The material is thick and it didn’t puncture, there’s no leaks. When the rubber bottom is on, you’d have no idea it’s damaged. It cleans extremely well, I only use water in it, but the opening is wide enough for a bottle brush. I love the handle, it’s easy to carry if I don’t have my bag.
