Description of Event or Problem · 0

I WAS INSTRUCTED BY THE FITNESS COMPANY WHOOP TO KEEP TIGHTENING THE BAND TO ENSURE IT RECORDED MY VITAL SIGNS PROPERLY. UPON DOING SO, THE DEVICE LEFT A RED MARK ON MY SKIN. WHEN I TOLD THE COMPANY ABOUT IT, THEY WANTED TO REPLACE THE BAND. I'VE BEEN WITH THEM FOR OVER 3 YEARS, AND THEY CHARGE $250 PER YEAR FOR THAT? WHAT ARE THE LONG-TERM CONSEQUENCES OF HAVING THAT BAND ON MY ARM?
