I use a thermometer that looks like a thermapen knockoff and costs about $15. I’ve used it regularly (but not professionally) for four years and I’ve seen it give the exact same readings, swiftly, as one more expensive thermometer of the same kind, a cheaper one, and a body thermometer to measure fever. What makes the Thermapen worth every penny? I haven’t had this break, but if it does I will probably order one of the same, which will arrive in a day or two without needing to (a) contact support or (b) send something in the mail. What am I missing? As a professional, what would you be missing if you used a cheaper model?

I think it is mostly an issue with quality control. I've had horrible luck with thermapen knockoffs. Temps all over the place, battery compartment loose, miscalibrated out of the box. If you found one that works, awesome! But I'd venture to guess that most people weren't that lucky.
