I have had one for over 10 years

I bought a bt-5 in 1990 and still have the same one. I use it periodically but not much anymore. I have gone through periods where I used it frequently, I used to use it for hangovers, but don't drink anymore. I still use the original headset and it works fine. I will probably buy a bt-7 since the price has come down. In 1990 it cost 500 dollars. Very effective device. Tweet
