Bests & Worsts Reviews from Amazon

Sound was only played out of one side of the stereo system in my car (Honda Pilot) with this particular adapter. I ordered the Car Cassette Adapter from RCA to replace this one, and it worked correctly (sound in both sides). I believe the difference is due to the size and/or position of the contact points on the part of the adapter that is exposed to the tape deck. As you can see from the attached picture, the working RCA model (top) has two contact points, covering most of the metal surface. The single-side only BESDATA model (bottom) has only a small connection surface, shifted to one side. Hope this helps.
