How long does it stay cold?

Around 15 minutes. It is a good product, but I think it is little expensive for the results!

It stays longer than 15 minutes. If you keep it in the freezer over night, it will stay frozen all day.

if you keep ice roller in the freezer over night, it will stay cold for many hours.

I'd say it stays cool just as long as my igloo cooler. I usually freeze some small water bottles to keep in the cooler when it's not plugged in.

I have used it twice for the same purpose as you state and it was cold 24 hrs later. Keep in mind the tempature of where you are using it will determine how long it keeps cold. I used it for a plane trip across country.

Depends on how cold the food is but usually less than an hour. And then it keeps it hot until you want it. I love it and use it almost daily.

I did not test it for twelve hours. The longest I tested it was about 3 hours, and the car battery was not drained. Everything in the cooler was still cold.

Not sure how long it will stay cold by itself since I normally use a freezer pack with my lunch. With the freezer pack my lunch stays very cold for at least 6 hours.

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

depends on your settings. it lasts me approx 24 hours. My heat has been running more than usual in this cold weather we have been getting. I can say I am happy with it. easy to fill, does a good job. I currently use it in my bedroom.

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

It's not insulated but if you add some ice packs it will stay cold for hours! The more packs the longer it's cold.

I don't know about how long it stays cold. I only use it in the microwave. It will stay hot/warm about 45 minutes.

yes. If you hear swishing around in there, it's not cold enough. Leave it in the freezer for at least 24 hrs. It takes a while.

Agree with many other responders -- stays warm for maybe 8 hours -- but definitely not hot after that. Insulation is present, but it's not like a thermos at all.

I'm guessing this cup would keep a decent temp for about 30-45 minutes if it's closed up. However, where I come from, in the winter, you don't let your coffee sit long enough to get cold, so I don't accurately know how long that would take. If you let your cup sit, you're not really a coffee drinker anyway, eh?

It keeps mine cold for about 4-5 hours but I have never used it for 6 hours. And yes it fits in my bag

Doesn't cool as well as an ice pack you keep in the freezer or even ice cubes in a bag or ice pack...mostly because it just doesn't last long. I'd say you have no more than like 10-15 minutes before this cold pack is no longer cool enough to be effective.
