The device is not only piano, the engine is actually barely perceptible only the sounds of angesauten air can not be avoided. The performance is good. The device can be used in all installation positions, wall or ceiling. The electrical connection is established above. Of course, the device can also be rotated when, comes like me, the connection from the left, but then you have to live with the flaw that the Maico emblem sits on the side. The device is made of a square piece, practical, good and available only in white. Good technique is paramount, aesthetics is not the strength of the device. What could the manufacturer nor generate additional business to if he would like to offer the manufacturers of electrical switches different caps, I would like to spend more for it. A weak point of the device is the suspension of the two flaps at the outlet. The suspension is so delicate that one must be extremely careful when already unpacked, especially during installation and fitting, not cancel it. I did not make it. The manufacturer's service is good. A question for installation by email, were answered promptly. All in all, a good technical equipment, with potential for improvement in the design field.
