we install the system 3 week ago . the rear wireless speaker work well and be the main reason we purchase this product over other - the design of we family room do not allow wire to cross it . the system also have lot of input and output -- we want to be able to add a VCR for we kid ' video and be able to hook on a external video camera . both connect well . during set-up , however , some more detailed direction that explain the various connection would be helpful . we want to use we own 5 disc dvd\/cd player instead of the single dvd player that come with the system and install this be not as simple as we have hope . get this to work require a couple of trip to Radio Shack and about $ 45 in additional cable . hook up all of the other component , however , be straightforward . overall , we be very pleased with the product . those who purchase the system and stick to the piece they give you will probably be even more pleased .
