Product review (5 stars): Accurate and tough
As soon as I received product I immediately put the sensor in my mouth...read 98.6 good sign. I then promptly tried getting it nice and clean looking in my sump and dropped it not once but 3 times, completely submerged in saltwater, I even face palmed the 3rd time and let it get a couple extra seconds bath. Proceeded to dry it out and replace batteries. Working like right out of the box. Until the corrosion ruins it, 10/5 and much much better than the most popular aquarium digital thermometer which I have destroyed about 4 of.
