They might be good enough depending on what you're looking for, but I ended up going back because they just didn't seem like value for money (finally I bought a fancy Bluetooth connected one). Everyone seemed to read a little differently, but I'd say they were all within a degree of each other. I managed to switch most thermometers to F but one refused to switch! The other didn't work at all. I bought these for greenhouse use and I knew they wouldn't hold up well.
