Great scale!

Dave Nolan

Works fast, seems pretty accurate. I like it over-all, and really like that it can be run off batteries or via the included wall adapter. The only thing I don't like too much is that it beeps pretty loudly when powering on or zeroing out.

This scale is very well built & thought out. You can easily select to measure in grams, ounces or pounds. While I won't be using the feature, it can also count units. It includes a cover that not only offers protection, but also serves as a bowl to contain ingredients. The large LCD is easy to read. And the best part, it includes both batteries & an AC adapter. The tare function works well. The warranty is 20 years. A must have for the serious barista.


This handy little scale achieves exactly what it sets out to do. I put coffee on it, it tells me how much it weighs - what more can I ask for? Unlike some of the cheaper scales from other online sources this one holds a zero very well and tares very easily. The only drawback, and it is very minor, is that the beep can not be turned off. If it bothered me that much there are instructions online to disable it, but that does void the warranty. So far it doesn't bother me that much. I would definitely recommend this scale.
