How long should one freeze to be effective?

It depends on your freezer, of course. I usually let it freeze at least overnight or for a long workday.

It actually depends on your freezer. I put mine in the freezer compartment of our side-by-side refrigerator and it freezes in a few hours. Our chest freezer doesn't work as fast. That's why I have at least two of these coolers on hand so while one is freezing, I can use the other one. Good Luck.

Couple hours at most. It doesn't stay cold all that long, but its ability to wrap is awesome.

Usually an hour. These are the best old packs I have found on the market. Enjoy:)

They stay frozen for 20-24 hours; freeze them until hard and they are good to go.

I have never had it freeze on me, but I would say it should be good. Ya might want to contact the manufacturer.

I froze mine. It has special extra long lasting cubes in the gel and will stay ultra cold for an hour. You will freeze before it thaws.

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

Yes works real well. What I do is to put a portion in a baggie. Lay it flat in the freezer. It will freeze as a flat thin block. Then vacuum seal it. it will also defrost faster than a thick frozen block.

indefinitely I believe. It doesn't take long to get them cold and they seem to stay cold/cool for at least an hour. I purchased two, so one is always ready.

I just leave them in the freezer until we need them. But they should be cold enough within an hour or two.

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.

A couple hours. They don't freeze solid, but they do stay cold for a while. I feel they work better than ice due to no melting. My wife and I use them all year to keep a small cooler, cold. They are great!

Yes, use rock salt and ice and churn for 25 to 30 minutes. Most freezers begin to groan as the ice cream makes. This one is powerful enough not to.

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.

Not likely I would say it stays cold anywhere from 20-30 min tops then you need to throw it back in the freezer to cool it back down, which also takes about 30 min to make it cold again.

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.

I have not tried to freeze them. And I don't think it would work very well. If the expanding liquid didn't break them, the extreme cold would probably make them more prone to crack
