This instant-read thermometer has spotty accuracy but very rapid response time. It also has an irritating “hold” feature that makes reading it iffy. It cannot be left in the oven while cooking. It has an auto-off feature that will power down the thermometer after 10 minutes. There is no backlight.

One of my pet peeves with thermometers is the predictive readout. Instead of reading the temperature at the probe in real time, they extrapolate the reading based on the rate of change of temperature, and “hold” that predicted value on the display. This prediction may or may not be accurate. This thermometer has a quick response time but obscures the result with one of these predictive algorithms. It frequently holds a value that is below the actual temperature. This is frustrating because you just don’t know how well the prediction is made. In my testing, I found that by pressing the button to release the hold, the unit would again estimate the temperature, more accurately with each succeeding press. Often, three presses of the button would give me the best results. Thanks, but I can think on my own.

The manufacturer’s contact info, including address, telephone number and e-mail, is found on the packaging. There is no instruction sheet beyond the information found on the package. The unit is covered by a one year warranty.

I like the fast response time but find the predictive approach to be inaccurate and potentially confusing. The display is easily readable and the accuracy seems to be good if you overrule the hold feature. It would be nice if this could be disabled, but it can’t. I’ll give it a Bronze medal, but use it with an eye toward its limitations.
