What to know before buying

Listing details to confirm

Listing precision details are expressed inconsistently: the details give temperature accuracy as 0.3 without a unit or sign, while feature copy claims +/-0.3℃, alongside +/-2% RH. The title and feature copy claim an 80M remote range, which is not independently confirmed. The listing describes tabletop mounting and also a hanging loop. Treat these as listing claims rather than verified performance.
