I couldn't even insert the supplied battery and couldn't close the compartment properly. When I held it with my finger, the thermometer worked. I then asked another family member to try the same result. Upon closer inspection, it turned out that the plastic molding was not cut at the factory. This only spoils the impression of the reliability of the entire product. I returned an item of better quality.
