Q & As

Monster High Definition HDP 850G PowerCenter 2 5 1 1
Should have been 5 stars I bought this from my local store to run my home cinema equipment. It was very well equipped and seemed ideal until I tried to fix it to the wall. It had four keyhole type screw connectors, except they were placed horizontally. The instructions said to drill four holes to match the larger holes, and to screw the pan headed screws and spacers into the wall, neither of which were supplied-place the unit over the the pan headed screw and press DOWN, to lock the unit, since the slots were horizontal, this would not work. The slots were so narrow, and such a tight fit, that even by attempting to move the unit horizontally it would not lock in place, so the unit was reluctantly returned to the store 25 January 2014
