The Thermomether functioning properly. It has four buttons: on / off, hold (to maintain the temperature display), ° C / ° F (very convenient because I have an American cookbook for Brittles & sweets), max / min (shows seemingly the highest ever with thermometer temperature measured). Basically, I am very satisfied with the purchase, especially since it, an offer for less than 7 - was. Two small caveats: The shipment was from England, which is why it took more than a week. In addition, the labeling of the buttons is provided on a glued plastic card that already easily triggered when unpacking and now (after 1 x use) has dropped. However, since the function is not impaired, and as long as that is not a measure of the processing of the whole thermometer, I am satisfied with it sticking firmly easy again.
