Query: Not ready for primetime

I bought this adapter so I could listen to my TV with bluetooth headphones. I returned the adapter for two reasons: 1) The place in the back of the transmitter where the line out jack is plugged in was flimsy; I had to push the jack in really hard to form a connection. 2) There was a sound lag that made watching TV while listening not enjoyable.This adapter is definitely "not ready for primetime".
