Do you need to know your tea’s temperature with super accuracy and immediate response? Do you want a thermometer you won’t ever have to adjust or worry about? It will just work? Then this is the massive thermonuclear overkill thermometer for you! Man, it works. And to be honest, it really changes how you think about cooking all together since you will inevitably use it for many other things but tea. But I actually bought this specifically for tea because I was tired of crap, broken, unreliable, impossible to adjust tea thermometers.
