I have installed the thermometer in my Watersmoker, it looks pretty and the scale is very good and accurate read. At room temperature, my copy meets the temperature quite well, in the most commonly used of me range between 90 ° C and 130 ° C lags the thermometer between 15 ° and 25 ° behind (compared to a calibrated Greisinger high precision thermometer). Therefore, it is seems to me of little practical use and the comparatively high price is not justified to me.
