Review: Perfect! - Great cup. My kids favorite color is purple. Keeps water cold. Comes with straw cap and extra straw + open spout cap. Great capacity. No leaks.
Review: Excellent bottle and worth the price! - I really like this water bottle. We have purchased five of them over the years and the most current purchase is replacing one that I’ve been using since 2019. There are several pros and the main ones are that if you fill it with ice, your drinks will stay cool for over 24 hours. We pretty much use ours for water so we don’t have to worry about ice watering our drinks down, but I’m sure if you put another drink in there like lemonade or a sport drink that it would stay cool even with less than a little to no ice. The second main pro is that you have two different types of lids: a straw type and the quick chug type. I use a straw and my daughter likes to drink hers with the big open chug style. The main con is with the flip up straw function, which is what I actually use the most. Sometimes a little bit of water will catch in the top of the lid after you close the straw, and it will spill out a few drops. It’s not very much and I’m kind of used to it so it doesn’t bother me much but it’s annoying at first.

### ⭐⭐⭐⭐⭐ Good product, recommended if you are looking for a smaller size flask/sipper

Excellent size for a child or if you are looking for a smaller tumbler/sipper. Insulation is great, liquid stays hot and cold for a while. My child is happy with this!
