Polder Instant Read Digital Probe Kitchen Thermometer 5 "Can't do without it" Mrs Roberts 18 March 2018 A great product. I've had mine for 2 years and wouldn't be without it. Great for taking internal food temperatures, oil temperatures for deep frying, dough and much more. I use it every day and I've probably only changed the battery once since I've had it. Initially, I couldn't find how to change from Farenheit to Celcius - but it is possible.
