Does it keep it really cold? how long does ice keep in it?

This is not an insulated bottle, ice would keep about as long as in a regular plastic cup or bottle.

It depends on the outside temperature. I would guess around 2 hours before the ice melts. It doesn't stay cold much longer than does an ordinary bottle. I usually encase it in an insulated carrier with a shoulder strap so I don't have to carry it in my hands. Once I dropped a bottle and it cracked. Mainly I buy these types of bottles because of the screw on/off feature so that I can fill it with ice easily.

If you have a cold pack underneath, it stays pretty cold. I don't think it keeps it cold on it's own.

We have only used ours to keep beverages cold. But it does that well with minimal ice melting for five hours at a time on average.

I put it in the freezer for 20 mins. It kept it cold for 15 mins. I hope this helped.

I am not sure as I use it for cold items. I do know that it keeps my drink fairly cold for about 3 hours until I remember to put it in the refridgerator.

It depends on how long you will be leaving the frozen items in the car. I live in a hot humid area and it takes me 20 min to get home from the store I have not used an ice pack and the cooler does a great job. If I have other stops to make I throw one in just in case. This bag so far does a great job keeping cold things cold even ice cream for at least 20-30 minutes no icepak

The unit gets cold very fast (even freezing). I haven't tested how long it stays cold after I turn it off. I leave it on in the car as the unit only uses energy when it needs it. It doesn't drain the battery like the cheaper ones when you leave it on.

I've been using this product for months; it stays cold a long time after I use it. So if I put it right back in the freezer, it I think it only takes a couple of hours to freeze up again. Honestly though, I've never timed it because I bought 2 of them (1 to take to work). So if you put it right back when you're done, the time to refreeze is short.

see my Youtube Review. https://www.youtube.com/watch?v=MaAeRlvsJG8 Its Not a freezer, but a well Insulated Box that holds about 25LB of Ice and keeps it for about a week. We have it Fill Up and then Shut it off for the week, or you can keep it on and have it make ice automatically when low. I do it my way because of Less wear and tear on Machine.

its insulated but it will only stay cold for about 3-4 hours. ice pack is best

Depends on your time frame and ambient temperature. It is not better or worse that other similar coolers on the market. If you are serious about keeping stuff frozen for more than a few hours you are going to need to pack with dry ice or invest in a freezer that can run off a car battery. For my purposes it keeps milk and meat cold for several days but I change put the ice every 48-72 hrs depending on how hot it is.

Yes, to both questions. They stay so cold oftentimes whatever is inside gets pretty icy. When I put room temperature liquid in it takes a few minutes to get it chilled but it eventually gets cold.

No, mine doesn't get "cold". It is cool to the touch but nothing more than a metal object. If yours is really cold on the outside, it might be defective. If when you shake it while it's supposedly empty and you hear it sloshing, it's certainly defective. If it doesn't keep things cold for very long, it's defective. Mine will keep ice all night long. Ice will melt a little bit but not all that much over time, which is the best thing about this flask for me. At the price, it better work.

It holds just a tad more than 4 cups, and amazingly does keep cold beverages cold for over 18 hours. I have only used it for beverages with ice, and I am extremely happy with it. Definitely worth the money.

yes..... I have left it in my car for up to 2 hours not wanting to carry it while biking or skating and it still hold the cold very good.

It works pretty good if you use plenty of ice. I generally use a blue ice pack and have a 32oz nalgene bottle that I freeze with drinking water. The cooler tends to sit in my very hot work truck all day, but by the time I break for lunch the nalgene is unfrozen but still cold and my lunch is still cold. If I don't eat my yogurt at lunch though it is usually too warm to eat within a few hours of lunch. So it keeps things cold about 6 hours, but only with at least 2 ice packs. It also seems like even frozen plastic bottles of water keep it cool longer than the hard blue packs.

Okay...had this for about a month...it keeps things cold, but if you want ice cold beer, you need to move them to the freezer (which holds about 3 bottles). The "freezer" does build up a small amount of ice, and it doesn't appear to be self defrosting.
