Extremely sensitive! Read ALL the instructions first.

This thermometer is VERY sensitive to environmental heat. When you first get it, set the thermometer down somewhere so you can read all the provided instructions and watch the informational video--if you hold it for longer than 3 minutes, it can affect the reading. I would advise testing on a healthy person first to get a feel for how to move the thermometer during a measurement, because pushing too hard on the skin can affect the reading too. Ear measurements are more accurate, but taking off the sensor cap can be a pain. In my case the battery cover kept coming off instead.
Though the thermometer needs at least 30 minutes to acclimate to room temperature, the actual reading time only takes seconds. The convenient storage case that comes with it is also a nice touch. Once I got the hang of it, the thermometer produced consistent results, so I definitely find it useful enough to keep it on hand.
