Best thermometer? Forehead or ear ?

Meghan

I have a dual forehead/ear thermometer. Amazon special I think. It worked for a while, now all of a sudden it will read two different readings, total different numbers, off the same spot and even in the ear - time for the trash! 🛢 with another little on the way, I want one that will last! Anyone use Exergen? Ear or forehead?
