Hearing Aids - several different kinds, all bad
I'm the at least equally pissed off wife of a pissed off consumer of hearing aids. First of all, the price is exhorbitant, and he's had several different kinds.
Second of all, they fall out easily and get lost, make his ear canal sweat when they do stay in, they emit a deafeningly loud electronic squawk, use up batteries at an alarming rate . .
. and most of the time, anyway, it's like sitting across the breakfast table from the silly old Vaudevillian who's continually going "Can't hear you; I've got a banana in my ear."
