THERMOMETER

Description of Event or Problem

TO: FDA, OUR DAUGHTER, (B)(6), BOUGHT 4 THERMOMETERS ON AMAZON, TWO FOR HERSELF, AND 2 FOR ME, NONE OF THEM WORK. THE MANUFACTURER'S INSTRUCTIONS SAY TO SHAKE THE THERMOMETER 20 TIMES. I SHOOK THE THERMOMETER 50 TIMES UNTIL MY ARM ACHED AND THE INDICATOR BAR DID NOT GO DOWN. I WANT TO ASK THE MFG "IS IT POSSIBLE FOR A SICK OR ELDERLY PERSON TO SHAKE THE THERMOMETER 20 TIMES? NEVER. I WANTED A THERMOMETER WITHOUT BATTERIES BECAUSE WHEN IN NEED TO TAKE THE TEMPERATURE, THE BATTERY MIGHT BE DEAD. SO, PLEASE HELP ME. I DON'T HAVE THE LABEL TO RETURN THREE THERMOMETERS TO AMAZON.
