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.

## Questions & Answers

**Q: Is the 24oz small?**
A: It's about the size around of a 16 oz plastic bottle of soda, but taller.  It fits in my cup holder of my car.  Don't think the larger one would.  Since it keeps ice so well, I often refill it with water on the ice still in it.  I don't consider it small or large.  Like Goldilocks said, It's Just Right.

**Q: Do you sell the chug straw lid separately?**
A: I had ordered a couple different 24oz pictured with chug lids, but I received straw lids. What I have eventually purchased was a 24 oz with both lids, to make sure I got the Chug lid! So ask your questions to make sure you're getting the right product :-)

**Q: Can I purchase a replacement straw lid for the Thermoflask?**
A: Yes. I just went through this for the 40oz Thermoflasks I purchased at Costco. The straw lids are not sold by ThermoFlask directly (on their website) but it is sold by their manufacturer, Takeya, for $10. Www.takeyausa.com

**Q: Is the straw lid insulated?**
A: Good question! The leak-proof straw lid will keep your drinks cold for up to 24 hours and hot for up to 12. It is not insulated.

### ⭐⭐⭐⭐⭐ 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!
