Much computer-programming-frills, probably to justify the price. Can be placed on roasting. But this plug at shoulder height is not only definitely too high, but also placed too far centered on the pad. Sometime in the night is to it. The alternative would be to move it as far to the edge that it overlaps slightly above the edge of the bed (and it is stopped with air to rest 70cm width). The plug of my approve discounter-part (that I no longer want to use because of the lack shutdown possibility) is both flat, as also mounted further outward. Does not bother. Beurer UB 90 packed after a night out and returned. Beurer: Why the plug does not attach to the foot (with a long cord!)
