Why is my temperature not rising up to max even though I already set it up to max and cup is already on it?

It works kind of like an inductive stove. It needs a flat bottom or flat metal bottom. The only time you would use a flat metal bottom, is that if you need to heat something up quickly. In addition, it won't work with insulated cups and/or double wall mugs or glass cup.

How sensitive is the gravity induction switch? I have used other heaters where the switch does not come on and does not work reliably.

The switch has never failed to work perfectly and reliably when I have touched it to turn the device on or off. However, I have noticed that occasionally the warmer will turn on all by itself. This doesn't bother me too much, but I'm sure it would concern most people.

I went trouble turning it on?? videos and looked at manual. i dont see any reason for a delayed start yet i can't get it to turn on easily. auto shut

Try to put the warmer on a hard surface and keep room at the bottom because it has a pressure sensing button on the bottom.

Will this work with 110 and 240 volts? can be used in europe or the middle east?

I doubt it. If the ad says it is 110 volts, that's it.
