Hand down the best prices scale for the price. Excellent ability to precisely dial in pour overs. I’ve been waiting a long time for a scale like this to hit this price point.

Accurate and easy to use
Size: 3 kg - Normal Size, Size: 3 kg - Normal Size
At the moment, I can't think of anything I dislike about this scale. The buttons are responsive, the measurements are accurate (I checked the readings with a couple of calibration weights from a scientific scale), the displays are clear. Operation in daily use is very simple. 1. Turn on scale 2. After self test, place carafe and filter 3. Press "T" to tare 4. Add grinds 5. Press "||>" to weigh the grinds. This automatically tares the scale again and sets the timer to standby. It also activates the coffee to water ratio display 6. Add water and the timer automatically starts so you get a precise bloom time. The added water is weighed and displayed as you pour and the coffee to water ratio display gives you an instantaneous reading, so you can brew your perfect cup of coffee each time. The scale has a large capacity and precise resolution so it works for single small cups to large pots. All in all, the best scale I've tried so far and might pick up another one when they go on sale (again). Highly recommended.
