The directions are unclear and the forehead directions seem to work differently to others (scan if from left to right on forehead). The forehead temperature is not consistent with ear, and has never provided a high reading even when there's a fever. I contacted customer service , left a message and number, no call back. I deliberately paid almost twice the going rate for a 'good quality' thermometer to be very disappointed. Life had been busy and i haven't followed up. No doubt I'll get a call back now. Hope so, so they can process a refund perhaps.
