How long does it stay frozen?

About 30 minutes. We have a few so if needed one is out and then another is in the freezer to replace. First one we got was at the dentist after my daughter had wisdom teeth pulled. The gel is soft so it can bend around a joint. We have had them for years and have even bought a few for others!

My husband uses it to ice his knees after taking a shower & before going to work. It slowly melts over a period of 2 hours, out of the freezer, on the human body. I used to take them in a small cooler for after physical therapy & as long as the cooler is cold to start with, they lasted about the same. I have placed them in freezer bags about the same size for multiple use. The seams on these newer ones are fragile, this way, if the gel starts to leak, you can still use it. We used the one he got at the hospital for 5 years--but we took really good care of it. That's how we got the name & information to get the new ones, but we didn't need a case. I'm glad amazon offers them as an add on. Saves $. My husband uses it to ice his knees after taking a shower & before going to work.

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

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!

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.

You cannot place it in the freezer, but the refrigerator; yes. It will literally keep anything cold for days.

I leave ice in it for a couple hours...but it isn't very frozen when I dump it into my freezer. It often clumps together Once dumped in my freezer due to it having started melting. Also if I use the ice straight out of the bucket it melts fairly quickly if its been in the bucket for a couple hours. If you dump it quickly the ice is fine. I don't think you could leave the ice all day and expect it to still be chilled. A few hours at max.

The longest I've left in the refrigerator was 4 days. I also don't use big quantities at a time... So mine stays frozen. One of those spoons to scoop ice cream works great. It allows me to scoop as much or as little I want.

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.

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.

It starts very cold from the freezer, and at 30 minutes it is still cold. My Physical Trainer says not to keep it on any longer than that, or it could cause an ice burn to your skin. You should wait at least two hours before using it again on the same area. It is not filled with gel, but I believe water, which when frozen lasts longer, and is colder.

We typically let ours freeze overnight and that works best. It does not work if it's only in the freezer for an hour or two.

I can't remember for sure, but I believe it was about 5 years at room temp. and 15 frozen.

I can't tell you how long after thawing, but I keep mine frozen, and I have had it in the for freezer over 1 year. It is still good, and the bottle has not expired. When I need some, I scoop it out like ice-cream and thaw only what I plan to use.
