Title: Works but don't expect great quality
Review: I bought the Irock at Radio Shack because I noticed the cassette adaptor for playing MP3s on my car stereo was not playing well through both channels. I took it home, put batteries in it, plugged it into my laptop, and tuned my FM to the needed channel. The sound was fair at best. I had to turn up my volume a lot to get the same sound level as my cassette adaptor. I could hear a high picthed hum, which sounded like some noise from the power source that was not filtering out.If you don't have any other method of listening to your portable device over the stereo, then this may be ok to use. But I took mine back for a refund.
Is the review positive or negative?
