Definitely worth it if you want a bottle that actually keeps your drinks cold all day.

### ⭐⭐⭐⭐⭐ Keeps Drinks Cold Forever….and the size is great for road trips.
*by A***A on March 8, 2026*

### ⭐⭐⭐⭐⭐ Water tight & well insulated
*by W***E on April 15, 2026*

These are the BEST water bottles ever. Im on my 4th - won't even consider a different kind. They stay quite cool in 75-80° temps for 10-12 hrs, if filled from fridge. (I've had 4 only because I eventually lose them...)

### ⭐⭐⭐⭐⭐ It's a Bottle. It Holds Water.
*by P***O on March 6, 2025*

The water bottle works great. It keeps water chilled rather well. If you're in it to save some plastic, great! It'll last you a long time. If this is your 5th one, I think it defeats the purpose of being "green." But that's a different conversation. How cold does it stay? Long enough. If you want it to stay cold 12-24 hours, that also defeats the purpose. Drink your water. Why do you need your water to be cold tomorrow? Drink your water today. What I love about this compared to other bottles I've used before or seen: * Wide Mouth - easy to add ice. Easy to drink out of. Easy to clean. * No Straw - no concern about getting Smoker's Lines. * Size - some other bottles of the same external size are about 32 oz vs. 40 oz. * Handle - Fun to swing. * Doesn't Spill.
