i have one of these rf units for my xbox..i prefer them more than the cables that now come with the systems because you can string one system to another with no problem and i have had no interference in picture or sound quality ever... so far i have 9 systems linked together including some old school systems(such as my genesis nes.master system neo geo saturn snes etc.. as well as my mint condition colecovision system) and the current gen systems such as the ps2 gamecube, as well the next gen systems such as my new xbox 360 :)

to the guy that said this product "does not work" he must not know much about video game systems or television outputs or mabey he got a defective one or better yet just read the directions its not rocket science..

It is either the RF adapter or the XBox but something just does not work right; there is severe sound interference some where. Nobody has any answers - not Micro$oft or whoever. I find that tech-support that goes beyond 'is it plugged in?' just does not work.

I find, for the most part (90% of the time), that NEW-TECH just will not work with OLD-TECH.
