How long does it stay on for?

There is a constant mist setting that typically runs for a couple of hours and an intermittent setting that runs for approx 6+ hours.

About 3 hours if you put it on the "continuous" setting, and about 6 hours if you put it on the intermittent setting.

Approx 2 hrs on the constant mist setting & at least 6 on the intermittent setting. Ivenever played that close attention to it.

One application will stay on for 1-3 days. However the longer it is on it can cause irritation. Once taken off it will not stick to use again.

Well, it depends how long you keep it on. In general, It lasts at least 9-12 hrs in a day when it's on, but if you use 'sleeping mode', it would be more than one day(at least one and a half day you don't need to charge it). Hope it helps.

It stays on until someone answers it (turns it off). I don't know how long it will stay on because I've always shut it off.

You can set it to turn off at 15 or 30 minutes but Itll stay in as long as you want it to without the timer.

Light stays on for about 2 minutes after being triggered. If you keep moving around, it will stay on until there is nothing there to set it off.

It stays on. You will need to unplug it in the morning or re-moisten the pad.

I've had it set for up to 60 minutes. I don't receommend you have it on for that long except under the lowest settings.

I believe it does not stay on. It only is in when it triggers. I'm sorry I can't be too specific, I don't have it anymore

I'd say ours last about 3 weeks, considering it stays on for a half hour at a time and we usually put it on 2-3 times a night it's not too bad but we will probably invest in rechargeable batteries for it. It is a lifesaver though!!!

Have had ours for 5 months. Leave it on all day and sometimes all night too. No problems so far.

It is at least 24 hours. Actually, I left it on one night and it think it said 37 hours and counting when I got back to it.

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.

That depends on how long it's been on. It will go off after 8 or so hours. But if it happens right when you put it on and it doesn't heat in about 1/2 hour or so, call Amazon and see about returning it for one that works. Mine goes on and I put it where I want it set and it stays there for approximately 8 or so hours. I can turn it down or up when I feel that is needed.

That depends on the setting. I've never had it on long enough to go out. I usually use it on the brightest setting and have had it last >90 min without dimming. I believe the manufacturer states that it can last 2 hours on that setting. Lower settings will obviously last longer.

It last a lot! I have kept it on for two days in a row. With nonstop use it can last like 10 hours

As long as you're moving, it stays on. If it goes off from inactivity, a small movement will get it back on. I haven't tested up to a minute, but from what I've seen I wouldn't expect a problem.
