It seems that many people have the dreaded red flashing light on one of its wireless rear speakers. Logitech sells more understanding not a wireless model. I'm sure there are others like me who are not willing to replace a wired version (option Logitech rebate). For those who chose to exchange or give up and buy, the alternatives you are willing to sell his work a rear wireless speaker, only a job? Hopefully this is a win-win for all.
