Mostly great, except one little annoyance
Color: Black&Silver, Color: Black&Silver
Pros- lightweight, small, very accurate, easy to clean, timer included. Cons- I use this to brew espresso on my Breville Touch and to get an accurate reading, you have to place something flat (structured) under the scale. Otherwise the reading just jumps all over the place. I know lot of espresso machines have the same base, so this might be an issue for some! This is my reason for 4/5 stars. It’s an easy fix, it’s just kind of annoying. Value for the price seems to be on point. It’s easy to clean. It has a timer as well as scale (nice for espresso). Buttons work the first time you push them. That’s it that’s all

Beautiful, functional, and perfect for a stylish coffee bar
I absolutely love this scale. As someone who cares about both function and aesthetics, this was exactly what I was looking for. It’s refreshing to find a high-quality kitchen tool that doesn’t force you to sacrifice the look of your space. The white and gold design is stunning and fits perfectly on my coffee bar without looking bulky or industrial. Functionally, it works flawlessly. I primarily use it to measure my coffee beans, but I’ve also used it for other items, and it’s consistently accurate and easy to use. The size is perfect — compact enough to keep out on the counter without taking up space, yet large enough to be practical and stable. The display is clear, the buttons are responsive, and the overall build feels solid and well made. I also appreciate how intuitive it is to use — no learning curve at all. If you’re someone who loves a beautiful, cohesive kitchen setup but still wants reliable, quality tools, I would highly recommend this scale. It’s small, stunning, and performs exactly as it should.

Great scale, an excellent buy
Color: Black&Silver
Is it possible to fall in love with a scale? I unboxed this one and, without reading any directions, put an empty 1/4 cup on it, turned the scale on, filled the 1/4 cup with coffee beans till I had the desired 17 or so grams, and turned the scale off. Easy-peasy! It’s small but sensitive, able to tell when a single bean has been added or removed. I almost didn’t get it because of the charging issue, but at least it tells you what the current charge is, and the way I use it I believe it will last several months without recharging. I’m so glad I bought this scale!

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.
