How long do they stay cold? I don't want to go downstairs middle of the night to replace it.

Like any other ice pack, I does not stay cold forever. If you're looking to have it stay cold overnight, this is not the one for you. I'm not sure of any ice pack that stays cold that long......?

The packs stay cold for an hour or so; you may need to replace; however it's not medically advisable to leave a cold pack next to skin for over 20 minutes. I do, but I wrap it in a kitchen towel to avoid frostbite.

I don't know I use it for heat. I would imagine maybe only up to an hour. I bought the things that look like blue peas and put it in the freezer. Stays cold several hours.

I try to turn them off every night to save electricity and so they don't disturb my roommate, but sometimes that doesn't happen every night. I had them on for a good 2 weeks straight. They still work. I haven't had a problem with them overheating.

Seriously doubt your drinks would be cold for very long in that situation. First, this isn't a fridge but a cooler. Myself, have never had reason to use this without it being hooked up to electricity. If you must unplug this while in use, suggest using some of the blue ice items to help keep your drinks cold. That should give you an hour or more.

I replaced mine cold and it worked fine. Came out easily. You are apt to burn yourself removing it hot.

I usually put ice in it. It is not insulated, so it won't keep them cold for a long time.

Sorry can't help. I keep mine in my basement all year long. The coldest temperature is probably 65 degrees.

It's probably too warm for a drink if you want the drink to stay cold. You could set it there for a minute, but not a place to leave it.

I got his for my dad for Christmas of this year 2012 but he hasn't put it out yet. We don't get as cold as that here any more but she is small and dainty enough that I would bring her in if you have a really hard freeze. I wouldn't trust leaving her out. We leave our more sturdy solar lights outside no matter what. Sorry can't be more helpful.

I didn't know, so I put mine in the freezer for 12 hours at minus 17 degrees F. They are still as soft and flexible as at room temperature! Amazing!

I've had no problem with them freezing overnight. Time-specific, I am not sure.

I keep them in my freezer. They usually stay cold for two days in a cooler. I also using them when I need to put ice on my knee or on my back.

I don't think they would last 9 hours. I use all 4 ice packs with an insulated bag. I even put the bag in the fridge the night before and pack the ice packs before leaving. I've found them still cool after 5 hours, but not enough to help the food.

They last probably 30 min or so, not warm yet but maybe not cold enough to be effective. I try and use them for 20 min before throwing them back in the freezer.

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.

Sorry, but I haven't taken them out since there were installed so i have no idea what the insulation situation is right now. To be honest i never thought of it.

Mine stay warm about 1 hour if I use them indoors and about 30-45 minutes if I use them outside in the cold.
