First, I must even say that it is this is a very nice system, although some parts are made of plastic. Disturbing was the fact that after installation of the transformer unauhörlich grumbled - sometimes louder quieter times. This deficiency I have reported to Paulmann phone and e-mail. Even after two days was a new, free humming transformer in the mail. I'm excited - here's kudos to Paul Mann. This can be experienced not so often. It should also be mentioned that the new, free humming transformer is black - the exterior cladding is equal. Possible that this is a new series of transformers commercially - this time to information to those who also want to hang a beautiful system on the ceiling itself.
