Query: Iffy

We've had this for two years and we still use it as a backup thermometer (as long as we have it might as well use it). My wife has always sworn that it reads low. The reviews that highlight the variability in results are somewhat correct in our experience. I just took my temp, for example, and got 97.8, 97.3, 97.8, 97.2 in the span of less than a minute for the same spot on my forehead. Still, in the age of technology we are all probably over sensitive to accuracy. Does +/- one degree make that much of a difference? We also have an ear thermometer which is the same kind used by the doctor's office when we bring the kids in and we experience the same variability with that. We have had the most consistent results with oral electronic thermometers, which are more difficult and time consuming to use but seem to be more reliable.
