Query: Just a cable would be smarter

I had to to end up reselling them on ebay and lost my moneyThis is why this product is bad:a)You can just use one at a timeb)Unreliable, it will just stop workingc)Why pay 100$, when it is smarter and cheaper just to by a speaker cable and run it to your stereod)Overcomplicated software and configuration
