Query: Not perfect, but the best FM Transmitter I've use so far

It's hard to please people in his product category because there are some many variables that can affect sound quality that are are to blame on the product. The degree of radio frequency crowding is certainly one of them. That being said this Coby works fine. I have it tuned the quietest frequency I could find in L.A. which is 88.3, but I still get some minor popping sounds. That does not bother me that much. Other than that the build quality is excellent. I like the blue glow from the LED display.
