The first time I bought it, the fm reception was so clear and awesome that I can get stations from hundreds of miles away. I bought it again since the first one stopped working, but this time I noticed that the reception went down dramatically. I can barely get any stations, including local stations, there is too much interference, and the volume is less sensitive now so the max volume is quieter than before. I noticed that the first one was made in Jan 2017, but the second one was made in Feb 2018. Is it that the second one was a defective one or was it that they changed their fm chip over time? I want to know as soon as possible and if you could give an answer, I would thank you for it.
