The package was open, I think through customs. But, everything is in good condition and complete. The package contains the thermometer, an outer probe and a bag. I tested, on me, as a medical product but I do not recommend it for this use. The privilege for a semi-professional activity. The ideal would be to make a comparison with professional calibrated equipment. Otherwise, he's fine.

Shipping 19 days. AAA batteries bought in advance. So far measured a maximum of + 212 and-11 degrees. Error +-1 degree. Body temperature understates by 1 degree. The boiling water temperature in the kettle showed 99.5. Good, useful device. You shouldn't expect superprecision. This is another price category.

Ordered 29.11.19 received 09.01.2020, the packaging is so-so, but the pyrometer is whole. According to the work: lies about 2-3 degrees (pan on the stove 102 gr., and water in it 98,5 gr.). Perhaps it is necessary to play the emission coefficient, because. Casserole and water materials are different and therefore the coefficient should be set different.
