This has been my 2nd digital thermometer to break within a year. My first was the JBJ thermo that goes inside your tank. That one didn't even last a month. I've used the digital ones because they're normally accurate down to +/- .1 degree, but that doesn't matter too much if its broken. Do you think I should just get one of those cheap-o marineland stick-on LCD thermometers, or should I replace it with another digital? Or do the stick-on thermometers ever fail as well?
