By chance we came across the Rommelsbacher heater, informed us on the Internet and finally decided on the slightly more expensive product - and have never regretted a single second. The build quality is excellent, the cord to turn still holds problems and so far we have not even missed, the device off again. We had quite a few cases in which the little girl had just wound and should return to bed, but then again made in the diaper. With a heater, which heats just ten minutes and then must be completely cooled down before it can be turned on, we would have been duped.
Longer Kuschel- or match deposits on the changing table would not be feasible.
A little tip for the hobbyist: We have the heater as the hospital attached with an angular design long on the changing table, so that the heat also arrives at the child. Even the midwife was excited about it.
