I ordered this back in March 2010. It's been just under 2 years and already I need a new audio adapter - sound is only coming out of one speaker. It was fine when it worked - sound quality was good. There were a couple moments of static, particularly near powerlines, but other than that - I had no complaints. I didn't use it every day, so I am surprised that it is no longer working as it should.I previously had the cheap cassette adapters that lasted only about 1 year, so I decided to "splurge" on this one. I've had friends that used FM transmitters and in particular the Monster brand, and they were enthusiastic about the quality. I expected that with the price and reputation, I would be granted a much longer lifespan than the cassette adapters. Yes, this did last longer than my past cassette adapters, but not nearly as long as I had hoped for.For the same price I could have bought 3 (maybe even 5 depending on cheap I wanted to go) cassette adapters and those together would have lasted longer than the less than 2 years afforded by this FM transmitter.Although I was pleased with the audio quality, I don't think the price was representative of the lifespan of this product.
