How long does it take to freeze completely?

I think this is in part a function of the temperature of your freezer. However, we found that we had ice in only a few hours. I received my trays mid-morning. Washed, filled them and put them in the freezer. We enjoyed cocktails that evening. My husband loves them.

I haven't timed it yet, but I would guess 3 hours. You get two trays, so its easy to have a full tray at any time.

I'd say a minimum of 4-5 hours. But we placed ours in the freezer over night.

No more than a couple of hours, but your freezer may vary. I keep mine kind of cold, but I store these on the freezer door, so that has a tendency to affect things on my end.

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!

It didnt take long to defrost. I did a trial run with this product. I placed it in a foil thermal wrap with a frozen ice container. Didnt last long, but my ice container was still frozen

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

I have had to use this many times and have never experienced any freezing. Always had a full vial when I used it. I can't advise you on a partial vial.

Do you mean before freezing? Shouldn't make a difference. Just takes longer to freeze.

It takes probably two or three hours to freeze all the way. It's about 9" by 4". That's a rough guess. But you should know that I found basically the same thing at Wal-Mart for only $9.99 and I like it a little better. It stays cool longer.

I don't know the answer to your question. I never timed how long the freezer stays cold. I did have the batteries die one night. Everything stayed frozen for several hours. That said, we love the freezer. It was the best item we put on our sailboat. Keeps our meats frozen. We even have ice cream.

No issues at all with it freezing up. used it for about 20 minutes straight and no problem at all.

I have not had that issue. I have had vials 3/4 empty and they did not freeze.

It freezes quite well. I have only used this cold by freezing it. And it retains the cold for well more than 30 minutes. The material in the bag is some sort of clay and it stays pliable even when frozen. So it is easy to use on your back, arm, leg, or other body part. When I put it in the freezer, I put it in a gallon plastic bag (folded in half with the cover left on it). It freezes in about an hour. When I need it, I pull it out of the freezer, take the plastic bag off, and put it to use.

Not the pre freezed ones. These takes longer but since it is very small, couple hours should do

Definitely - esp if you wait a few minutes after taking it out of the freezer

As soon as the cooling cycle stops. I think that is usually about ten minutes

I have not done that yet. You may want to try it first. I do use these a lot, I just never froze them. Sorry I could not be more helpful.
