I have checked other thermometers in my house and they are definitely accurate. It takes a few seconds for the temperature to change, for example when I take it out of the tank to test new water, but I usually wait a maximum of 10 seconds. I chose this one because it's small, easy to hide, digital, battery operated, and turns on and off to save battery. When it comes to tank thermometers, this is a steal. I recommend!
