Does it shut off automatically after a certain number of hours?

No, the mitts need to be turned off manually when you are finished with them. They do have low and high heat settings you can control.

My husband uses these often and they really help. He says they do not shut off automatically.

Yes it does. After a certain amount of time it shuts off. I do not remember how long that time is but it does shut off by it's self.

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.

No, its set for a certain amt of minutes and turns off after time runs out.

There is no automatic shut off, just on and off switch. So, as long as you have it on...yes.

It said it had an automatic timer on it, but I have not noticed it shut off by itself.

Yes. I think it shuts off after an hour (maybe this is adjustable, I haven't checked).

To my best knowledge, it does not. Nothing from the manufacturer indicates an automatic shutoff. But then, the longest I've used mine is 45 minutes.

I do not think it has automatic shut off. I never leave it on more than the normal use.

No automatic shut off. However, there is a timer. You set the timer and then the unit will shut off. That comes in handy for me.

I do not think it will automatically shut off. The sound is too high pitched to let it go for very long. I immediately unplug it when the alarm goes off. Hope that helps.

Yes it does. You have the option of setting it to go to 2 hour auto shut off or setting it for continuous heat where it does not shut off. There is a heat setting for each option that goes up to level 6.

The first set of buttons are timers. 1hr, 2hrs, 4hrs, and 6hrs so it'll automatically shut off.

It has an automatic shut off, though it does not take 4 hours for it to shut off. I believe mine shuts off after 2 hours.

It has an automatic shut-off. I think it turns off automatically after an hour. Move the switch to off and turn it on again.

Yes, it has an auto-off feature. Not sure how long it stays on but it automatically shuts off if left unused within 5 minutes.

Yes, fantastic feature! I beleive it automatically shuts off after 60 minutes.
