I did give this contraption 1 star basically out of pity. I could barely wait for this gadget to arrive, and was really looking forward to hearing music on my long ride to work, instead of yapping disc jockeys. I plugged the thing in and nothing. I twisted and adjusted the power plug thingy in and out until finally the light flickered on briefly, only to need further readjusting before it would stay put. I turned on my music, which was barely audible under all the static, didn't matter where I set the volume or which station I tuned to. Still hopeful, I tried the thing out on my way to work, thinking local interference could be to blame, and it might clear up as I drove. Instead, the situation only became worse, as an ear shattering feedback noise erupted from my speakers at random intervals. At this point, I was greatly concerned whether or not my speakers were still intact. Was lucky there, but realized I'd wasted my money, and packed the thing up for return that day. Guess I'm better off putting a new belt on my old cassette player...
