In order for our little mouse has it during winding toasty warm, we needed an additional heat source. Sought heaters and many found. From cheap to expensive something is indeed represented, so I kept me a little of the reviews and tended to middle class. The Rommelsbacher heater is processed well and safely, comes quickly to temperature, is easy to use and to assemble, and should not be missing in any baby !! Tip 1: 2 min turn previously, then the changing mat is wonderful preheated. Tip 2: note the well-to-understand assembly instructions as z.Bsp. in our changing table, there is a structure which would hinder the heat radiation for wall mounting. Remedied by a shelf (with two angles at the bottom) on the changing table. Positioning of the angle or the radiant heater possible depending on the required heat radiation. Of course, should this reasonable for mounting hex screws etc. are used .... an hour with minimal technical dexterity 1 work Tip 3: Buy all ... Baby's want it: o)
