Bought this system about a month ago and I'm very impressed with it.
The box it comes in is extremely lareg and heavy but it packs a whole load of kit into it. Construction of the stands is pretty simple (a screwdriver is all that is needed) and can be done with no-one else helping.
Wiring up the various speakers, aerials etc is easy also as everything is colour coded.
The rear speakers are wired together and get their signal from a "sender" connected to the main system. This "sender" is about the size of a pack of cards and relatively inconspicuous. If you do want to turn it back into a "wired" system, the cabling is still supplied.
The system itself is very easy to use and the sound you get out of it is great.
Overall this system is great value for money for a DVD player, surround sound system, radio and wireless rear speakers. Highly recommend it!
