Excellent purchase for the price I paid.  Works great sending signal from my computer to outdoor location (approximately 50 feet through a wall with window).  It is a little testy when I first turn it on, often requiring slight adjustments to the tuning to find the proper signal frequency.  Every once in a while I think uncontrollable outside static also causes issues, requiring me to readjust the frequency on the transmitter and receiver.  But once working, I've rarely had to make adjustments--and it plays just fine for hours.
