Only believe the price, then the quality of the equipment

I was only a little skeptical at the price really a good device is to be expected, but it's true in this case: Good is not always expensive.
The installation is very simple, the assembly instruction course. Since we had the angle adjustment slightly too small, we have the heater mounted on a board and this brought angled against the wall, so that now counts all of the heat on the changing table. But is not absolutely necessary.
After turning it within seconds warm on the changing table, the heat is transferred evenly, after turning it within seconds again cool.
The 10 minute shutoff enough for easy diaper change from perfect. If you continue to play with the child in a little hot or intends to carry out a baby massage, you just have to move to the shutdown 2x the ribbon and the heater is immediately warm (so no cooling of the child).
The ribbon is unfortunately really be a bit thin, so far there were no problems with it.
Conclusion: Good and cheap, I recommend the device you.
