I'm a landscaper and I fill this with ice and water every day.  It keeps my water cold for about 12 hours which is more than I could reasonable expect.

This is my first bladder and it did not fail me. Large opening so I could put ice in there and have cool water for a while. Also, no leaks when the hose is removed.

I put one of these chillers in our child's insulated lunchbox and it remains cool till lunch.

She comes home from pre-school and it's still partly frozen.

We haven't had any leaks.  They've held up very well.

We've been using these for lunches for about 6 months

This was a great price- no leaking and keeps water cold for hours. Easy to throw in a gym bag!  A great size too.

I have had this hose for 9 years.  It has withstood freezing temperatures, including the coldest winters we've had in 100 years.  It has been stretched, coiled, pulled around corners, stepped on, and generally abused as a garden hose can be.

It hasn't leaked.  It doesn't kink like other hoses I've had, and it outlasted the outdoor faucet it was attached to.

It is so good, I'm buying one for my relatives who just bought a house.
Excellent, excellent hose.

Very good insulator! Water was cold the next day after being in a car in the sun at 70F. No leaking and durable bottle

Compared to the Igloo models, this thing is just amazing. I had to get used to being able to put it on its side and not just assume that it'd leak (it doesn't). Drinking from it is also a no-drip process.  Keeps liquid cold, and is super cheap. Also no chemical odor to the water unlike the Igloo, even if left for several days.

It held up over the winter! No leaks and it was a very harsh and cold winter (-27 F) the wind was strong too. It stood the test!

Does a good job of keeping liquids cold and it truly doesn't sweat. The attachment it comes with fits well but I wanted to use the flip lid and it makes the bottle leak... but the one it comes with fits fine.

Easy to fill and clean. Never leaks. Hose stays pliable even after being stored in my summer house all winter.

I own two of the 'older style' bottles and I LOVE them so much, I had to own the 'new style' as well.
I must have my water freezing cold. No lie, if you put ice in this water bottle at 9am- there will still be ice in it by 9pm. I've even left it in a hot car for hours, only to come out and find the water is ice cold and still has ice in it.
And- this bottle doesn't 'sweat'. Condensation on the outside? Never! It's wonderful!

I got one of these for me and one for my mom for Mother's day. We both LOVE them. They d not sweat AT ALL, they keep our water EXTREMELY cold, and they fit in our cupholders. This bottle will replace all the other ones I have. I am very satisfied with this product. I am very impressed by the quality.

Have had other heated water products in the past and none have really worked. Seen this one and reviews were a little mixed but I thought I would give it a try. Recently here in PA we have been going thru a cold spell with temperatures below 0 so I expected this water unit to freeze. When I went out to check on it much to my surprise the water was not frozen. I like the design, its easy to fill, it does not leak. I definitely recommend this unit.

Gotta say this WaterVault Stainless Steel Water Bottle sure does work like nothing I have ever seen before. You see I live in Arizona and right now the temp outside is at a constant 3 digits, 100+. The other day it was upwards of 111 degrees and I had to do some errands running around town. I filled this up with water and ice. Wouldn't you know I was out all day, I left the Water Vault in my vehicle while I did my running around, by the time I was done over 6 hrs later, the water was still ice cold and there was still ice in the vault. I think the only possible con I would have is foe the size of the opening, it's a little small but not impossible to clean, it's not a big gripe but if I have to find a negative, that would be it.

Bottle keeps your water cold for a good 2 hours on a 90-plus degree day. Water tastes pure without that "fresh from the garden hose" taste you get with other bottles. Top is easy to secure and I have never had it leak or squirt out on its own.
