Review: オシャレでカワイイし結構冷たいのも長持ちしてました！表面が細かく凸凹してるのも持ちやすくていいです。
Review: After 6-9 months of light use, my Hydroshield water bottle is a major disappointment, looking as though it's "come out of a warzone." The primary issue is its abysmal durability and finish. The paint has not held up too well at all, chipping and flaking all over. Furthermore, the bottle dents very easily and is covered in scratches all over, which quickly makes it look old and heavily used. For a reusable bottle, this lack of resilience and poor finish quality is simply unacceptable. Based on this experience, I strongly suggest you look at buying something different if you want a water bottle that can withstand the rigors of everyday life.

## Questions & Answers

**Q: Re Hydro Flask 24", what does "flex lid" mean?**
A: no, you can't. if you watch the video it shows that you have to remove the lid to drink. i think the "flex" is in fact that the handle folds down, instead of being "fixed".  you can get a lid that has a pop-up straw.

**Q: Ok so does it come with little stickers?**
A: Hi - Wendy here from Tall Ridge, the exclusive authorized seller of Hydro Flask products on Amazon - Thank you for your inquiry! Our Hydro Flask products do not come with stickers. I hope that answers your question.

**Q: Curious... is the bottle supposed to be perfectly round all the way up and down?  i just received mine from amazon and it is not.  it feels oblong.**
A: Yes, it should be perfectly cylindrical (round) all the way up. If it's not, there is an issue, and I would think that the company would take care of it. To tell if it's in fact round, remove the cap, make sure it's empty, place it on its side on a flat surface, and roll it.

**Q: I just bought this hydroflask in the color olive. Is it normal for the lid to have to be forced to close all the way? It doesnt close easily**
A: How did this work out for you? I'm experiencing same problem? I know it's not normal as I have been using this brand for a couple years now. Did u keep and use?

*by M***S on 4 July 2023*

I love Hydroflasks! I bought this to replace one that I had been using daily for years. The old one had taken a real beating! It had several dents, and the coating was starting to chip just a bit. I love my new one! Same great Hydroflask quality and vibrant color! I really like the top which is easy to loop a finger or two though for carrying! It also fits well into my car's cupholder and the cupholder of my day pack!
