Bests & Worsts Reviews from Amazon

I have used a TV Ears Digital system for several years. Aside from a miserable process of replacing the battery in the headset, it worked well. However, it finally gave out and I bought the new version of what I thought was the same thing. I have an ordinary television set with cable and DVR. I installed the new system the same way I did the previous one, but when I listened to it I heard a delay between the TV Ears signal to my head phones and sound from the television. It worked fine with the mute on, but my wife might object to the lack of sound. It was unusable. When I finally got through to a tech person (they aren't in their office on week ends), he suggested a work-around with my television, but my roughly seven years old Panasonic lacked the proper setting ability. He then asked if I had bought it from Amazon (yes) and intimated that the Amazon version was inferior to one that I could have bought directly from TV Ears! Also, every time I turn on the television I get electronic gibberish through the head phone. This is corrected by pulling the power source and re-attaching it or doing the same thing with the fiber optic cable from the television to the TV Ears device. I have no desire to go through that routine every time I want to watch television. Was this Amazon's fault also? This is not an inexpensive device and it ought to work after making a few simple connections with little fuss. I will return it.
