I have seen no trials which directly compare these aids to prove your repeated claims that one is better than the other. In fact I have not even seen a post yet by anyone wearing Signia Primax aids. You need to be very careful making claims you cannot prove and advising people based on your reading of manufacturers claims and “white papers”. These are not peer reviewed journal articles and are often little more than advertising. You write in a manner which may confuse new members into thinking you are a trained professional giving advise based on qualifications. I do not believe that is in anyone’s best interest.
