I bought that exact FM transmitter about two years ago. It worked, but the sound quality was not very good and I do not use it anymore because I could not get a decent signal from it over 30 ft. I spent a lot of time trying to tweak it (trimming the antenna lead, experimenting with difffernt frequencies) and I could not get it to sound decent. I decided that if I were to get one, it would have to be a much nicer one like they use for schools, gyms, etc.
