Thermometer works great, is constructed well, and measures accurately.
My only negative is that the fittings are not that tall, and make it difficult to mount on some plate chillers. I have a Duda Diesel chiller, and bought this with hopes to measure the wort out temp. Sadly, because of the height of the water in port adjacent to it, I ended up using this thermometer to measure wort in temp, and had to go with a Blichmann Thrumometer for the wort out.
