This is the worst digital thermometer I have ever owned.- There is no on/off button and it's intended to be a clock as well. If I wanted a clock I would have bought a clock. I don't want to have to put new batteries every time I need to use it.- It's quite complicated to use. I needed the manual to change the settings.- It's slow. I would not use it for candy making as I'm 100% sure that once it indicates the right degree, it's too late.- I've owned it for 3 months and used it less than 10 times. It's already broken, the thermometer function does not work anymore (and I was very careful with the probe).
