Beautiful accessory, legible, well crafted, seeming robust: German quality, not Chinese! Unfortunately, the displayed temperature values are systematically lower than 20 per cent actual temperatures measured by other means whose accuracy is known. Also the rise in temperature of the thermometer is particularly slow: more than half an hour to display a stabilized temperature! Given the many glowing reviews and more for this article, I probably came across a "wolf" who escaped manufacturing quality control in production. In conclusion, here I am at a loss to the advisor or to discourage other potential buyers.
