I had a precision oxo which was more expensive than this one but not great though, it would register .4 grams suddenly and not sensitive to the 1-2 bean increments. I bought this one for espresso specifically and man it is fantastic so accurate, super responsive, well built, size is great if you want to weigh your shot under your portafilter. I have a fellow series 1 and it’s amazing working with it. Overall highly recommend and for the price it’s amazing great value! Not sure why would I buy a bookoo for $130 or a fellow scale for $200. This one works great for $40

Just a tiny, accurate scale

Color: Black

Works flawlessly after I calibrated it compared to my other. Out of the box it was (very) off. Now it's within .1 of a gram. It's far more responsive than I expected. It's perfect for espresso and it's tiny so it fits on the smallest drip trays.

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.
