Hi. I have had a Beechband for three weeks now. The battery lasts about two and a half hours before giving up. I can only wear it for about an hour before it drives me nuts. I haven’t felt any different when I wear it but it is early days. It drives my dog nuts too as he can hear it. It’s as loud as a mobile phone on vibrate. You can watch the seminars on line. Once you buy a Beech band you will get invited to join the zoom meeting. I hope it works for your husband. I am still a work in progress. Geffino.
