Pull & Pour's Black Mirror Basic 3 review describes a coffee scale with a built-in timer, touch controls, an LED display and USB-C charging. It also lists brew modes that can support pour-over or espresso tasks, including functions such as automatic timing or taring. The features should be considered in relation to the procedure you intend to measure.
The author's impressions of responsiveness and stable readings are useful review context, but they are not equivalent to a calibration test performed by BeanScene. Stated precision, displayed resolution and verified accuracy are related but distinct ideas. A scale also needs to support the complete load safely, including the cup, brewer and liquid rather than only the dry coffee dose.
Check platform fit, readability, charging arrangements and the exact mode behavior before buying. A feature intended to automate one step may be inconvenient if it triggers at the wrong moment in your own process. Compare the scale with the tasks you repeat most often: weighing beans, recording beverage yield or following a pouring recipe. A straightforward interface can be a practical advantage without proving that it is the right scale for every setup.
