Low quality materials and it is not very accurate in measurement. The neck is loose, so one end moves during measurement and sometimes it loses it. The ON/OFF button is pressed relatively easily and sometimes stays on, resulting in battery drain.

Almost no reliability in its measurements, you have to press the reset every now and then to see something close to the actual measurement. The battery cover comes off very easily by accident.

Reliable is the only battery cover with its backward pull it comes out.
