Does anyone know if the MediSense Xtra Glucose Meter and the MediSense Optium are the same Meter?

I HAVE TEST STRIPS FOR THE OPTIUM METER BUT DON’T HAVE THE METER, AND THE MEDISENSE XTRA LOOKS JUST LIKE THE OPTIUM METER. JUST WONDERING IF ANYONE KNEW IF THE OPTIUM STRIPS WOULD WORK IN THE XTRA METER. IF YOU KNOW PLEASE ANSWER, OR IF ANYONE KNOWS WHERE I CAN PURCHASE AN OPTIUM METER, I’VE ALREADY CHECKED EBAY.
