Up until we bought this we were using a cassette tape thing that let us play music from our phones. The sound quality was awful! Then I purchased this little gem and the difference in sound quality is night and day! Not only is the sound clearer but this device has a plug to charge your phone (so no worries about losing the place where you normally charge your phone in) and it has an output plug as well. It is very easy to set up and use. The screen is very easy to read both night and day and I've never experienced any issues with the FM station that I tune it to. I read in other reviews that people were saying there was interference coming from the radio station that they were using. It may be that if you live in a very highly populated area you might have interference. I haven't had any problems with interference even when I'm driving in and around. So I'm not entirely sure why some people had that issue?
Overall, I highly recommend this product!
