Awful product! Heats up on level 3 to what can only be described as \'warmish\', on level 1 you can barely tell it is on. Not comparable in any way to other microwaveable heat pads. I returned this item as, for me, it appeared to be faulty - I am assured by Healthcare4all that they are all like this!! Very disappointing.
