How long can you keep them on?

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.

I've had ours up and on most of the time since we purchased them this past summer (we have them strung on the shelf under the TV). So far, no burned out bulbs, but just like regular (i.e. non-LED) xmas-type lights, you can always replace the individual bulbs.

I've had mine less than a month. they serve as my son's night light and they burned out after a couple of weeks. very disappointing as i don't have the ability/ingenuity or time to take them all off and figure out which is burnt out. REALLY disappointing for a $27 string of lights!

I wear them 3-4 hours with no problem. Maybe take breaks? If you're wearing glasses, they might need adjusting.

They last quite awhile actually. I change mine out weekly, even though I never see more than minor wear on them.

Depends, I guess. Standing and walking a lot with these on might compress them permanently and lessen the effects of the item. But these should last for a couple of months depending on usage. (Not a product professional answer.)

It depends on which setting you use. They really are only good for a night or two. Having said that, I refill the pads myself with 4 drops of eucalyptus essential oil and they will last indefinitely.

I can wear them for about 30 minutes with socks. After that, it starts hurting. Anyway, you are not supposed to wear them for too long as this makes the glands overactive.

Yes, they should definitely last that long. I would guess the 12-16 hr estimate seems accurate if not longer. My kids go to bed by 8:30 and have left them on overnight and they are still flashing in the morning.

No certain amount of time. I have used these last one several months....I just use them until I think they need changing or they have started trying to come off the belt. Just a use your on judgement...

I would say a couple of hours at night but for at least 3-5 days depending on how dry your heels are.

Never an issue. I sometimes have them on for 7 hours while I sleep during the day.

They are not permanent. They stay on for about 2 weeks for our very active dog, so we've never run into that problem.

I just used mine for 8 minutes and they are still cool..I love to use MagicGlobes around my eyes..very soothing!I'm ready to put them back in the fridgeafter 15 min.

Since they are hard to put on and take off, I often sleep in them. I went three of four days oncewithout taking them off. That left me with a painful rash around the top of the socks. If you are already wearing them 24 hours a day, that isn't a question that you need to ask.You have answered your own question.

These sanitizers stay on automatically for approximately 15 minutes. I agree with Amanda LC, I run at least 2 cycles, and I make sure I move the sanitizers to allow the UV light to get to all the inside area of the shoe.

I've only had mine for a month or so. However, I'm certain it depends on how often you use them and how well you take care of them after and between each use. I expect mine will last longer than 6 mo. as I don't wear them constantly.

They do come on during the day ,stay on for about 15-30 seconds. We have had ours up for about 2 weeks so far. They work well for us.

Indefinitely as long as you store them in a safe place. You should keep them some place where they will not be exposetto temps above 80 degrees.
