does it keep water cold

No, it is not good for keeping drinks cold. For that, I would recommend an insulated bottle such as the Hydroflask.

No, not really cold water. Just uncomfortably cool water. My sons and husband use them when we go to the beach in November in Florida's panhandle.

The water usually gets cold in about 10 mins or less, however the water doesn't get super cold. Cold enough to be satisfactory, but there is no adjustable temperature for people who like very cold water.

R u putting cold water in? Don't expect it to cool warm water. Mine keeps cold water cold for at least 20 hrs.

I think I keeps my water cold/ cool for several hours. Not ice cold but it does stay cool. It is quite large for Milk.

Does what stay cool?; this is just a hand pump, not a water cooler. It maintains the water at room temperature

No. It has a smooth edge and the water does not stay inside. It works well for us.

This is an educated guess, it will keep water from freezing but not too long, as a function of the air temperature and wind chill factor. A thermos flask will do a bit better.

It probably depends on it you put ice in it. My ice water keeps ice in it at least 6 hours. I never use it without ice so I hope I helped in some way. It also depends if it is in a hot environment. But it does have good insulation. :)

Yes, but it doesn't stay as hot as something cold would stay cold. It's still very good for short trips, school, etc.

It works very well. The insulated hose buys you time before it freezes. However, if it gets very cold, you can simply blow into the hose when you're done drinking, so that the water in the hose (especially the mouth piece) will not freeze.

Unfortunately no, but you can just as easily put cold water in it and run it without worrying that its gonna heat up. The heating thing only keeps hot water warm for a short period because its not meant to actually heat up the water.

No. It's a price of junk and so light weight it wouldn't even hold water. Mine went in the trash. Don't waste your money!

No, it does not. You would have to let it cool down and then put ice in it (or vice versa).

Not at all :-) The water stays cold but it's a little small but that might be perfect for others but I would have liked if the cup was bigger and made in USA. Best cup I've purchased so far.

No. But add a lot of ice cubes and keep container out from direct sun and your drink will stay cold.
