this is not the best for espresso as it requires a large base to get consistent readings. But it is excellent for what it is and more suitable for other coffees like v60 etc

The scale for coffee preparation is zero. To weigh kilograms or hundreds of grams is ok.
You put, for example, the container you want, you zero it, you put it back in the same spot and it will show a difference of 0.5-2+ grams. If you don't put it back in the same spot, you easily see differences of 2-4+. This makes it absolutely unsuitable for espresso, especially where 0.5 and 1gr are important (let alone more) and unjustifiable for a price of 15E+.

Update: In less than 2 months of careful use, the left side of the touch screen stopped working.

Average scale for making espresso because its response is slow and sometimes you may have zeroed the weight of the cup, not started the extraction, and the scale reads 0.2 or 0.3.
