how many hours does cold water last?

That's a very subjective question. It depends on how cold the water is when you pour it into the bottle. Also depends on what's the temperature outside the bottle. If its freezing outside then the bottle will keep the water cold for hours/days. If its a 100 degrees outside don't expect the bottle to keep the water cold for more than 30 minutes. If you put the bottle in the oven that's heated that's another story. So where do you want to take this bottle?

If the water bottle is sitting in room temperature it last about 2-3 hours.

Currently using it the required 20minutes following surgery but I would say it stays very cold about 45 min. Very moldable.

6 to 8 hours. I set it in a large coffee cup next to my bed and there is about 1 inch of water in the morning.

At least six hours. I fill mine up about 1/4 put in the freezer when it gets frozen I put cold water over the frozen ice and it will stay cold 8 to 10 hours or longer. I love mine.

It lasts a solid hour at least. I've left it out overnight rolled up and the center was still cold in the morning. It lasts a lot longer than most other ice packs I've used. It's a great value for the money

I believe 4-nice and big,well made,cold only lasts for approx. 10 minutes though. Check out the Donjoy Ice system.

I usually put ice cold water in at night and it stays pretty cold until morning. I'm not sure how long ice last depends on the area it's being kept. I use one at work as well and ice cold water is placed in it at 9am and last till I leave at 6pm still cold. Hope that helps

Varies. One example: about 97 degrees, water fresh out of the store fridge, stayed cold about 20 min, still cool just over an hour later, still refreshing enough 1.5 hrs later, and then I ran out and refilled. But - that's one of the reasons I bought me a small one like this one!

For about an hour - the first 20 - 30 mins are very, very cold - which my back likes. I think it was a great buy - I just wish it came with a cover. You need a towel or something from all the water it makes while defrosting. Hope that helps.

Not more than 3 hours. I actually use it to retain hot water. and it stays warm until 3 hours.

I'd say 4-6 hours. I love it. It also keeps drinks warm, it's our number 1 travel cup we use in this house. Whether filled with coffee, tea or water. Works great. Also, keeps ice in tact for hours.

Several hours but it also depends on how hot the liquid is when you put it in. If you keep the lid closed, it also helps keep liquids hot. Really good mug.

cool water is not the strongest sent, So I would say 4-5. Also does not last long maybe 2-4 hours.

More than 3-4 hours. Havnt tested it for that but distilled water is super cheap to buy so isn't a concern.

about 8 hours, maybe longer. The key is to have a WIDE, tall glass of water.

I have only used it for cold items. With an ice pack it stays cold for about 6 hours.
