About the Hot Dog Roller 5 Rollers, the hot dog can't be heated in the machine all the time, it will be burnt. If you need to keep the hot dog on the machine after it is cooked, you need to turn off the heating and rotating functions. In addition, if it is left for too long, the taste will deteriorate.

Hi, I'm not for certain if it could stay on all day. However, throughout the duration of my events. I will keep it on. This is really a great item.

Yes, If they last all day. We put dogs on for a party and the kiddos ate on them all night!

Low works fine. depends on how u like them. just keep checking them.

350 degree in front to cook and 130-150 degrees in rear to keep warm

no

I just put them in there raw and they cook good.

Pre-cooking them is not necessary. I just put several on about 15-20 minutes before company and asked that when someone took a hot dog to please add a new one to the rollers. That worked perfectly for the entire afternoon. (Unless everyone needs to eat at the same time) In which case I would choose another item to serve, besides the hot dogs.

We did not and they turned out great.

No there is no need to .
