So far no data on battery life, but otherwise, 5 *****
Very impressive at handling background noise.  I have been buying these in this price range for a long time, and was never fully satisfied.  I am NOT going to deal with a $3,000+ hearing aid  salesman, because I fear my temper will land me in prison.  Intense advertising budgets for these imply "WAY too much markup."<br />For me, the fatal flaw in all the ones I have tried is handling  competing signals.  I would get in the car, my wife would be talking, and as soon as she turned on the radio, I would remove the hearing aid, and put it away.  It seems they all gave the entire sound spectrum the same priority in setting the gain.  I don't know how this does it, but with the three programs, it was possible for me to select the best one for my particular problem. Tonight for the first time, I was able to converse with my wife while the AC was running and the TV was on.  OK, I just ordered one for the other ear.<br />All I really question is how many charge/discharge cycles the battery is good for.  That will be the limit on the lifetime of these.  I am SO glad to be rid of those tiny batteries the others took, especially on the units where you open the battery door to turn them off. The battery falls out, of course, and is generally lost. It is a horrible nuisance.<br />The ONLY question or issue I have is the expected lifetime of the unitHow long have these been out?  I'll see if anyone started a discussion about it.  Otherwise at present it's 100% 5 Stars.
