The operation is very simple: Lie on the mattress / sleeping pad, pull Spannbettuch about turn. The temperature of stage 2 and 3 is intended for the heating, the level 1 to the normal lying thereon. Well, in any case, the switch-off, so that the heat bed is turned off after 3 hours.
From the size I have to agree with the previous speakers: it is nowhere in the product description that is not the entire surface of 150 cm x 80 cm is heated. Of this I am, however, also gone out and disappointed by the wide unheated edges. Well, the heater itself does so, but nevertheless, I feel as a little deceived.
Positive consideration is that the electric underblanket is machine washable at 30 ° C. The operating element can disconnect it. The safety instructions in the manual should be read in any case! Not that someone burns the Wärmeunterbett.
Overall, me the product Medisana HU convince 665 Wärmeunterbett, the costs to the size of a star. The rest fits.
