Simple yet easy must have for discerning coffee drinkers
Color: Black&Silver
I seem to never get the same results from my coffee machine and it varied even more with the new brand that we just bought. I now have to make more adjustments with the water temperature, based on age, type of beans, etc. That affects the amount of ground dispensed and consistency in the shot until I get a new batch dialed in. So the only way to regulate these changes is to weigh both the beans and water. Using this little scale has made things easier, less frustrating and more predictable. What’s awesome is that it will automatically begin the timer with the first drop and stop when the pressure remains constant. Simple yet easy and super convenient. If you are looking for a great little digital scale this should do the trick. Highly recommended.

Great Digital Scale!!
Color: Black&Silver
The Maestri House S2 scale has been clutch for dialing in my espresso shots. Memphis heat or not, this thing stays accurate and steady. The timer starts up quick, the readings are fast, and the compact size fits perfectly under my Breville without feeling cramped. It’s built solid, charges by USB‑C, and the precision really shows when you’re trying to get that perfect pull.

Has fit perfectly into my morning espresso
Color: Black&Silver
This seems to me to be an excellent small kitchen scale. I am new to the complexities of espresso making and have begun using this scale every morning to measure my dose and output. It is working just fine. Easy to operate, keep clean and store. I did not give it 5 stars because I have limited comparisons but I don’t expect and will not bother looking for anything better.

Perfectly fits what I needed for my espresso habit!
Color: Black&Silver
This Maestri House mini coffee scale is a great little tool for espresso and pour-over. The size is compact enough to fit under a portafilter or cup, and the 0.1g accuracy makes dialing in coffee much easier. I like the built-in timer, rechargeable USB-C battery, and clean black-and-silver look. It feels precise, practical, and easy to keep near the espresso machine. Great value for anyone who wants more consistent coffee.

Maestro House Mini Coffee Scale
I have begun to drink tea, pu’erh tea to be specific. I have several varieties and I have had a problem with getting consistent results. The varieties can be very different in size depending on when the leaves are harvested (leaves harvested in spring are much smaller). So the easiest way to get consistent results is by weight. This scale is very easy to use with a ceramic tea scoop, set the tea scoop on the scale, zero it out and add tea leaves. This has made my results much better, without the wild swings in strength I had been getting before trying to eyeball even measures. This scale gives me accurate measurements to one tenth of a gram.
