Delivery took place as usual very fast through Amazon. The IF-extension should be done in a Hülsta sideboard 2.70 m long with left and right side sliding doors. After unpacking came the frustration. The cable with the Blaster-LED is not like on the Marmitek site and the manual indicated 3 m long, but only 2 m. Only the recipient has a cable length of 3 m. So that the cable for one side was too short. At first I wanted to return the item, after contacting the seller, who was very hard, but also could not help you, I've been thinking to test the product on a sideboard-side and since everything works fine. The small receiver is inconspicuous in the closet and 4 units (Denon amplifier + tuner, Blu Ray player + switchable electric. Socket) with the door closed properly bedient.Für the other sideboard page I have made England a 2.5mm jack extension ordered by 2 m and assume that then collapsed. Unfortunately, the standard jack is therefore difficult to get 3.5 mm and, in the local shops there is no such thing. The ordered from England extension costs incl. Shipping below 4.00 and that is acceptable. It is a real pleasure, with the doors closed all devices unobtrusive to use and I can only recommend the article. It can be observed also no service delays that scrolling is done as before quickly through my MP3 files.
