Review on KitchenTour Coffee Scale With Timer - Digital Multifunction Weighing Scale With 3Kg/0.1G High Precision - Pour Over Drip - Espresso Scale With Bright LCD Display (Batteries Included)-White by Pamela Jones

Overall, I'd recommend this device for accurately measuring coffee beans.1/10 gram accuracy helps get consistent results when measuring beans for espresso. For me, it replaces scales with 1 gram accuracy, which was not sufficiently granular, for example 17.0g vs 17.9g will get you different results when making espresso.I could only compare it with my existing scale up to 21g. They both showed the same weight.The scales don't offer a way to reset or calibrate themselves. Don't get confused by the video on the item's page.The stopper function is good for poor-over or french press, not so much for espresso. In particular:* It counts up from 0, never beeps (not a timer)* It can only be triggered by pressing a button, not by weight change. This means it can't be used to measure espresso extraction time, unless you manually press a button.
