Quite good, fast and accurate enough for home use. Popular last time cos cheap and not many alternatives at that price point. Think you can also calibrate it at times after going into a mode and using specific weights specified in the manual.    Load cell limit is 1.8-2kg. Means total weight you can place over the scale is that - including cup, vessel, etc. Go over the limit, got chance to damage the load cell if it bottoms out - like overloading shock absorber. This applies to all scales though.   It has internal battery - you charge via USB-C. 

A mix of everything from SEA.
