A really nice scale at a budget price!
Color: Black
Does a really nice job for a budget scale! I had an Amazon basics scale (which works great and I still use!), but I needed/wanted a tenth of a gram for weighing Moka Pot water and coffee. I can put this scale on my water dispenser, measure out exactly what I need, then put the Moka Pot filter (in a glass jigger so it stands up :-) on the scale (with a magnetic espresso funnel) and measure out my coffee. It holds up to daily use and is accurate. Nice job for my first "professional" scale :-)!

Solid little workhorse
Color: Space Grey
Works well. Key part of my espresso setup. Battery charge lasts. Easy to use. My only gripe is that the power switch can be hard (for me) to turn on and off without lifting it up to find it.

Worth it!
Color: Black
A necessity for anyone trying to elevate their espresso making game. I use this to measure my beans and to also measure the shot I pull and how long it takes to pull. It’s great quality and totally worth it. The scale is very quick to start when the shot starts to pull. Easy to use and a great scale.

Works prefectly, accurate, easy to use, and looks great.
Color: Black
I didn't expect much but it works really well and seems to be very accurate. It's much more sensitive (to 0.1g) than the scale I was using to measure my coffee and the autostart timer works really well. Also, unlike my other scale, this one is USB-C rechargable and so far has no indication of needing a recharge after a week or so of daily use. My other scale uses CR2032 batteries and goes through a pair every three weeks, so being able to recharge instead is quite nice. It's small and I can use it to time the extraction and also use it to measure out heated water for tea, or whatever I need. This is definitely a steal for the price.

Great value and full-functioned.
Color: Black
This is a simple, elegant little scale with timer. It's perfect for use with a small espresso machine like my Breville Bambino Plus. It shifts easily from counter use weighing beans before grinding, to placing on the drip tray to time and weigh shots. The top is smooth and water resistant. I think it's a great value.
