How long can you leave it on? Minutes? Hours?

No more than 15-20 min. Actual facial massage session should not be longer than 7-10 min.

Several hours usually. At least 4. I normally leave it plugged in over night and unplug it in the morning if I see it's done. I ride to work, and leave it plugged in for most of the day while working.

No, I normally only turned the unit on while at work, approximately 8 hours. I did leave it on for about 12 hours once. I only had the unit around a week before it malfunctioned.

it says in the directions to hold the 'on' button down for 10 seconds to turn it off. Which is what we do. I didn't know it turned off after an hour, we've always done it manually

yes it works up to a maximum of 12 hours when u have it timed. Other wise it stays on as long as you wish when you are not using the timer. Never a good thing to let anything run while gone just in case there is an electrical wiring fault... I always turn my things off after leaving home. I just feel safer that way.

The time greatly depends on the brightness of the screen. At a moderate intensity, I'd say 4 - 5 hours.

you can set it to turn off after 1 hour, 2 hours or 3 hours. or you can set it to just keep going until all the liquid in the diffuser is gone.

The one I have goes up to 19 hours. For all practical purposes you can go to 19 hours, 59 minutes an 59 seconds or 20 hours.

I have had 1hr 15 mins out of it. You do need to leave it on charge until you need it. Even leaving it off-charge over night reduces the burn time.

I don't know! Sometimes I leave mine on all night and other nights turn it on or off during the night. I absolutely love it though. So glad I got it. I ended up getting two. Do you want it on more than 10 hours?

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 use my for childrens church and never left it on very long, so I tried it today It was still on an hour after I used it. But the Kids and I really do like it, if that helps :) Good luck

I have not timed it but the on off has not been a problem. I would say it is reasonable and handy in all ways and I have not noted a problem with the length of time to off. I put it up to store without worry.

According to the user manual, this feature can be left on up to 12 hrs. I have not done that but have had it on for several hours without any problem. I like this feature for that second or third cup. And it is a hotter temp than can be met by using the microwave.

I have with no issues at all--I usually leave it on 30-45 minutes. Not sure if it matters or not but I figure longer has to be better, right? GREAT PRODUCT ;o]

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.

Yes, you can set it for 14 hours. Just press the tabs down for when you want to timer to go on and off.
