    Precise and durable
    Color: Birch
    Best coffee scale for the price. No crazy features which makes it very easy to use. Small enough to store in a drawer and durable enough to not worry about it breaking. Scale is very precise which makes it great for V60 and Chemex

    Great Coffee Scale
    Color: Onyx Black, Color: Onyx Black
    Absolutely love this coffee scale! For starters it was so well packaged. It is definitely worth what you pay for it. It has a silicon removable mat that fits snugly over the top of the scale. That makes it easy to pop it off to clean if you spill on it. The scale responds instantly to changes in weight which helps to give you accurate pour over results every single time. The scale also includes a built-in timer with a count-up or down control. It also has an auto shutoff but gives you plenty of time before it shuts off. There are multiple units to choose from when measuring. Overall just a really great scale and I'm so glad I purchased it!

    great scale (read tips for its super sensitivity)
    Color: Onyx Black, Color: Onyx Black
    in hopes this will help anyone else who bought this scale- this thing is super sensitive to vibrations. if your scale is getting off calibration for seemingly no reason, make sure the sides and the back aren’t touching anything else and that the bottom is on a flat surface and it will fix it entirely, trust me!! but aside from that, this scale works absolutely perfectly. it’s just the right size for my morning coffee, has great battery life, and is really straightforward to use. plus the silicone top makes it really easy to clean and looks nice on my countertop. the timer is super convenient for making coffee, this is an amazing scale for this price point

    1 year review: Excellent coffee scale
    Color: Onyx Black
    I bought this about a year ago and have used it daily ever since. The scale is easy to read, fast to update, and is precise. My previous coffee scale cracked from the repeated heating from my v60 carafe even with a silicone pad within 6 months. This scale has endured and I'm quite happy with it's durability. It's accurate and precise enough I actually use it with my bread machine as well. It's a nice, low weight scale overall. Cleaning is fairly easy, I just wipe down with a damp cloth. You can pull the silicone pad off and wash it more thoroughly if you want. My only down side is that I find the batteries drain a little quickly. My normal kitchen scale can last years on a button battery, while I usually have to replace the batteries here every 6 months. I don't use the scale for more than 3-4 minutes at a time daily and once or twice a week a second time per day, and whether the battery life is due to the brightness of the display or the polling frequency of the scale, it's a minor enough quibble to not ding it's rating. It's not a cheap scale, but it appears to be one of those "buy once for a long time" investments. If you're serious about coffee dosing and measuring your water for pour over, it's easy to recommend.

    Excellent coffee scale!
    Love this scale! The display is pleasing, high-contrast and very clear. It has a silicone cover, and there are zero gaps around the screen and buttons, so it's easily cleaned and I don't worry about damaging the internals with water or crumbs. There is a tiny bit of float, typically less than a gram, and only occasionally. For example, I'll weigh out 19.3g of beans, seal the bag, and come back to 18.9g. It's minor enough and infrequent enough that it doesn't concern me at all. The readout is quick and responsive, and I love the timer. At first it seems a little confusing to switch between counting up and counting down, but after doing it once I have no trouble with it even half-asleep. Just hold the units button, press it again to change between modes, and use power & tare to set minutes and seconds if counting down (use play/pause to confirm each setting). Takes less than 10 seconds. Overall it's quick, accurate, and well-made. I love that it has a much smaller footprint than my old kitchen scale, and looks sleek on the counter. Perfect addition to my coffee station! I also highly recommend their gooseneck kettle if you're in the market ☕
