Product was as described. Works well. I use it for measuring the amount of coffee for my drip coffee maker. I have not done any testing with respect to actual accuracy so cannot comment. But it seems close to the other scale that I have that only measures to the nearest gram. Construction seems good. Nice looking unit.

Nice scale

Color: Black

Works as expected, nice size. Makes a big difference when adjusting espresso extraction. I haven't used the timer. One improvement for my use would be to move the power switch from the back to the front, on the side or on the control panel.

Best Mid Priced Scale on the Market!

Color: Black, Color: Black

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.
