THNX 4 THE INFO. I GUESS I NEVER REALLY THOUGHT HOW SERIOUS ALL THIS COULD BE. AT 1ST, THE SAID IT MIGHT BE A UNIT MALFUNCTION, BUT WITHIN 24 HOURS THEY SAID NO, IT WAS THE REAL THING. I JUST THOUGHT I'D BE PASSED OUT B4 THIS THING EVER WENT OFF. ANYWAY, IF THEY HAVE TO TWEAK IT EVERY 3 MONTHS, THAT'S OKAY. BUT, YEAH, 4 SUCH A LITTLE UNIT, IT HAS A KICK LIKE A LIVE SPARK PLUG WIRE. I THINK IF I'D EVER FELT ANY OTHER CHEST PAINS MAYBE I COULD'VE SEEN IT COMING. BUT EVEN WITH MY HEART ATTACK 18 YEARS AGO, I'VE NEVER HAD A CHEST PAIN. ONLY A HEADACHE. AND U CAN'T BE SUSPICIOUS OF EVERY HEADACHE.
AGAIN THNX FOR UR FEEDBACK
