It definitely keeps my water cold. My son liked it alot so, I guess I will be buying another one.  It is larger than I expected, definitely not a cup to keep at your desk. It's for an event like a soccer game/practice.

I love this water bottle! I don't like drinking from plastic, and glass water bottles just seem impractical to me. The stainless steel is the perfect option, and it keeps my water cold. The caribiner clip is a great addition as well. While it would be good for being on the go, I am currently on crutches, and that clip allows me to easily get my own drinks...such a huge thing for me!

I use this every day and it keeps my water cold just as long as is advertised, usually without even precooling it! I filled it with ice before leaving for a trip, and when I checked it 4 days later half of the ice was still frozen!

I love the design and it does keep your water cold for hours. Only wish it were a bit larger. But I knew the size when I ordered it so cant complain.

So far I love this water bottle! It doesn't seem to sweat or leak at all which is great. It has kept my water nice and chilled. The grip on the lid makes it easy to screw on tightly but still get it off easily. I like its nice simple shape and design. I really like the white one I got and the 40 oz. size is great for me. I will probably be purchasing a black one in the same size as a back up and a blue one for my boyfriend. :)

I am in love with my new Hydro Flask! It keeps my water super cold and does not sweat. I only have to refill it once or twice per day and I drink all the water I need that way. Plus it is environmentally friendly, saving tons of plastic that disposable water bottles are made of. It is well worth the $40. I highly recommend this one!

I have been carrying this water bottle everywhere that I go and it is totally worth the price. I only use this for water because I can't imagine trying to clean up the residue left from juice or coffee at the bottom. I love how it keeps my water ice cold for hours after I fill it and I don't have to worry about it leaking in my backpack. If they weren't too expensive, I would have tons of them in multiple colors. Very happy with my purchase!

I love this water bottle!  It definitely keeps things cold.  Haven't tried hot yet, but last night I filled it with ice and then poured cold water over the ice.  Still icy when I got up.  Refilled it with cold water and it lasted well into this evening, with a couple more refills.  I plan to buy a couple more.  For the price, it is well worth the money.  The only reason I didn't give it five stars is because the lid isn't attached to the bottle, which will be a concern for people who will be using it out and about.
