So I bought the eflex 660 for my USA loop system. They did not send me the outside of the glass magnetic disc . Only the half attached to the head. I know it says to separate them , but there is nothing to separate . The part is missing I’m calling and emailing the company with no response yet :/ can use any powerful magnet from Home Depot for the outside. Until I can get the right piece ? Thanks. I waited for this to come and now it’s here and I still can’t hook it up …..
