Listen Up Personal Sound Amplifier
This Bell & Howell amplifier was one of many selected for trial for a serious need--oncoming deafness.  I tried MANY and this one really worked--for ONLY $18.00 AND I spent $4500 on \\"professional\\" hearing aids that didn't last 2 months.  I'll buy many more of these and STILL SAVE MONEY!  COULDN'T GO WRONG!
