How long can you keep this on? Does it get damaged after elongated periods of time?

I bought two and they each have stayed on for a couple of hours with no damage. I must qualify this statement, however, by saying that I've had these mug warmers only about a week.

The longest I have had it on was 12-14 hrs (several times) when I forget to turn off at night. There was no damage to the warmer or surface I had it resting on.

I have 2 mug warmers at home, bought from dollar stores years ago. They are still working till now. I have always left a stainless mug of water on one of them 24/7 to have warm water always available when I need some (instead of using a thermos bottle). In the morning I use the other one to keep my coffee warm. I add cream and sugar to my coffee so after a while of warming the coffee, a film of cream forms on top. So I have to turn off the mug if I know I will not be needing the remaining coffee for a while. When I feel I'm ready for the rest of my coffee, I just turn on the mug warmer again, and in a few minutes, I have my coffee. I have 2 mug warmers at home, bought from dollar stores years ago.

I keep this plugged all the time. I turn it on when I place a cup and leave it for several hours. Usually I have it on for 3-4 hours, but there are many times that I left it on more than 5 hours, and it seems to be fine. I even left it on over night by accident, but it was fine, ...although I don't recommend it.

I work between 10-14 hours a day and leave it on the entire time 6 days a week. Not one problem. Except maybe my extensive power usage due to my love of coffee. :D

I've had mine on for about an hour at it's longest. I don't leave it on without something in the cup, and I don't leave it unattended when it's on. The switch is very convenient for turning it off and on as needed. It also heats up very quickly. I've been using it for about one month, so I can't verify durability. It seems to work well, except it's not quite hot enough.

This warmer does not seem to be bothered by staying on for long periods of time. Sadly I have tested this on about three occasions when I forgot to turn it off, and it is still going strong.

there is a velcro connection that rips off the first time you use it. If you can sew the velcro on instead of gluing it, there might be a chance of it staying on.

Once you wear it, with the help if your body heat and insulation of your clothes it should last for 30 to 45 minutes.

I usually keep it on for 20-30 mins, and it stays plenty cold. I haven't kept it on longer so I'm afraid that's as far as I can offer information.

I have worn mine for up to three hours at a whack and haven't had any problems with it. It is adjustable for headsize, so you can loosen it up if it is too tight. I believe I could wear mine all day without a problem, but have no need to since my work in the woods is usually only for several hours at the most.

It's a little tough the first few times, but it's do able. Once you get it on, you can leave it on for a while without having to take it off. While you're unstable after delivery anyways, you'll post likely have someone to help you if you need.

Yes, not a long term fix. Once i put it on, the effects last for about 8 hrs.

We're only used it a couple of times and it didn't cause any damage. For extended use you might want to put some sort of pad (rubber or leather), just to help dissipate the weight a little. I hope this helps.

Yes that is true. They do "overheat" but since this is not a mechanical version it takes longer. believe the limit is two hours. Why you'd have it on for that long, I think you're safe.

yes, it lasts longer than i thought. If you don't keep in on all the time, it will last quite a bit. I still use them.

I have left it on my body for 3 weeks and then it was resistant to pull off. Still very attached. But I also had a tegaderm type cover over it so that it was not in contact with water. That might make a difference to the amount of time it would stay.

We actually use this sometimes to secure rubber feet on some of our equipment. However it won't be permanent, but may be as permanent as superglue or another glue (I haven't found anything that really holds those feet permanently!). Probably last a 3-6 months , or more, mainly depending on use. The tape does eventually loose it's grip.

I haven't had to use it in a while, but it seems like it was at least an hour and I kept it in the freezer. I started using mine a few weeks after having hip surgery and was really happy with it. It was easy to attach and adjust, and stayed in place once i put it on.

I am usually able to keep the sleeve on for a solid 20 minutes and any longer after that simply depends on the ambient temperature. I am very satisfied with this product!

We have done that with no issues. Technically it says on the packaging to remove it after twelve hours, but we've seen no signs of issues. Just make sure it's not too tight etc

Has anyone been using this beyond 3 months? How long has it lasted you and why do you continue to use it?

I know 3 4 weeks with it still being viable but I'm not sure how long after that though. I suggest if you do keep it cool not having it wear it can get worm.
