HEARING AIDS DID NOT PREFORM VERY WELL. ASK FOR A RETURN NUMBER,RECIEVED SAME AND NO ADDRESS TO RETURN HEARING AIDS. FOUND RETURN ADDRESS ON PACKAGE AND SENT ITEMS BACK.NEVER RECIEVED CREDIT OR ACKNOLEDGEMENT THAT AIDS WERE RECIEVED BY HEARTECH. THE BEST WORD FOR THE HEARING AIDS IS "THEY ARE JUNK" THE WARRENTY IS "JUNK".BUYER BEWARE. User's recommendation: DON'T WASTE YOUR MONEY.
