Product was as described and meet my need for a scale measuring 0.1 g
Color: Black
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.
