I love these thermometers. I have used many types of aquarium thermometers but these are my favorites. The wire is long enough to run through the bottom of my 100 gallon tank, right where I want it. They don't last as long as I'd like (usually about a year) but for the price it's not bad. Also, I cannot guarantee that I have never wet the thermometer case. I think that's why I lost the two I have. They are MILLIONS of times prettier than any other mercury thermometer that attaches to the inside of an aquarium. They are easy to read, read quickly and are accurate.
