As previous speakers, I am actually quite satisfied with the device. Only I use is also after 6 months still a mystery why the beam angle can not align vertically downwards (ceiling mounting is not permitted). The unit is in proper mounting only able to max. Emit 45 degrees downward. This means that the winding ends that he gets a nice hot face but the little nappy-Pooh remains at the head of more "underexposed". Although the heat is sufficient for an installation height of 1 m above the changing table for the baby just like this, but of the entire 600 watt Power output I feel always whopping 500 watts superfluously in the face! Why? When the unit is mounted 1 m above the changing table and 45 degrees radiates down, then hits the beam with the highest energy density about 1 m from the wall at the table level on. For a normal changing table of 75 cm depth, most of the energy goes so smoothly across the table, close to the wall (head end) remains cool contrast.
So therefore my recommendation in the attachment: Attach a little deeper device, but the changing about 0.5m move from the back wall.
Conclusion: Too bad, good device. But 60-70 degrees beam angle would have saved a lot of energy!
