I bought a different model of handheld thermometer from the same company. I hate thinking about all the money I wasted on cheap thermometers that constantly needed to be replaced. Buy once, cry once.
Love my Thermapen; mostly use it for grilling. Biggest regret is that I didn't buy it until I went through about four $15-$20 "cheapos".
Just used mine for the first time- BEST BREWING BUY - all-grain is way easier now- and much more accurate. If anybody is thinking about getting one, stop thinking and just do it!
Love my thermoworks thermometer. Never looked back.
Just so you know my grey one is faster than any of yours!
