does it stay on all night or go off by itself

two of the reviews state that it shuts off in 20-30 mins... and two answers here say it stays on????

It it supposed to turn off after 20 minutes but I haven't figure out how to do that yet and was too lazy to read the instructions. But even when it stays on all night I only change the batteries about once a month or longer

No. It's either on or off. It doesn't automatically come on. Great idea, though!

Hi there.. If you are talking about the projection, it will not stay on all night. It will only stay one for a short period and then you will need to hit the button again.

Yes, it will turn off by itself. It does stay on about a minute or so. I have never timed it. I would suggest using rechargeable batteries.

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?

It will stay on when it is plugged in until you turn it off or use the timer to turn it off for you. I hope this answers your question.

It's an on off switch so it only goes off when you turn it off. We use them for years all night.

Yes, it will stay on all night. There are 2 positions for the button: ON for 1 hour and ON with no time limit.

You have to manually shut it off and on, even when the diffuser auto shuts off the night light will stay on.

Not exactly sure how long mine comes on each night but it does come on, off & on throughout the night, and I have had my first one over a year and have not changed the bulb yet.

The machine stays on all night, unless you use the timer, ie. set it to go off at 30 min, 60 min, etc. I just leave mine on all night, usually on white noise or waterfall sounds. I use it every night; one of my best purchases ever.

It stays on whole time at 50% reduced brightness through out night time and when motion detected it brighten to full 100% brightness. It stays completely turned off during day time. It's all automatic. So far, it works pretty good past one & half month in use.

After the timer turns off you have to set it again. The longest timer is 180 min. There is no setting to keep it on all night.

The light stays on until you turn it off. This means you can't just let it completely shut off by itself. Not so good in my book.

It stays on all night. You can control it with the on/off switch as well. I honestly never used the timer.

It does not have an auto shut off as far as I know. I have left it on for more than an hour and it has not shut off.

They stay on all night unless you turn them off manually. The batteries last a long time too.
