## Before you buy

- 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.

## Customer feedback

Customer feedback describes the humidity meter as easy to set up and working well, with positive comments about app functionality and value. Connectivity experiences are mixed, including reports of poor connection, while battery life and outdoor suitability are concerns. Those reports matter for a Bluetooth monitor that relies on app access, alerts and battery power. The listing's range and measurement precision remain manufacturer claims, not guarantees of performance in a particular setting.
