How accurate are the readings, and can I rely on this monitor for important decisions?

The device offers useful real-time guidance and a clear readout, but reviews show readings can be inconsistent. Use it as a trend indicator and cross-check with other meters if precise measurements matter for you.

Does it require calibration, and how do I handle long-term accuracy?

Calibration guidance is not clearly documented in all reviews. If calibration steps are provided in your manual, follow them; if not, contact support for instructions and keep an eye on sensor drift over time.
