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.

Premium experience from a scale
This scale is not cheap, but it comes with a premium experience. The overall build quality is excellent, and it looks and feels great. Scale is extremely sensitive and response, and very consistent. Quick to zero, quick to turn on. Display is clear and easy to read. Well insulated from water, with only the bottom being semi-exposed to liquids (note that it is NOT waterproof, so still be careful - do not submerge it).
It also has an espresso mode which can be toggled on/off. That mode will automatically tare when placing things on it, meaning you can weigh your beans, take off the bowl and put back on a cup to brew the espresso into, all without tareing manually. It also detects when you're actually brewing, and it does so by detecting a steady flow of liquid. This specifically can be a bit finicky, it may or may not work for you depending on your machine and how you brew.
My only single complaint is the volume of the beeping. By default it plays a loud beep whenever you're using the touch buttons. It is very loud and I turned it off immediately. Unfortunately it seems there is no way to lower the volume on the beeps. Not a deal-breaker at all for me, but something to consider if you care about audio feedback.

Reliable scale, great for starting on a budget while still getting fairly solid results
This scale performs wonderfully and is very reliable. I will say the only issue I am having is that it seems to be very very touchy with not getting an exact weight reading and flickers a lot. I don't think this is really an issue as it might just be super sensitive. But for the price it's absolutely worth it

You Don't Really Need This, But...
This combination coffee scale and timer works exactly as advertised. It measures weights up to 2000 grams with 1/10 gram accuracy. The scale has three operating modes: espresso, pour over and manual. In espresso mode, the scale will automatically tare after a cup is placed on it then automatically start the count up timer and weigh incoming espresso as it starts to pour. In pour over mode, it will automatically tare after your cup/dripper/filter is in place. Then it weighs out the coffee dose as you add it. After you tare again manually, the timer and scale will start as you pour hot water. This allows you to let the saturated coffee grounds off gas for the desired number of seconds before continuing the pour. Manual mode is just that. You control the tare function and start the timer yourself.
Battery capacity is great so USB charging will be infrequently required. Accessories include a short USB-A to USB-C cord and a clip-on silicone heat shield to protect the scale from hot espresso. Coffee spills are easy to cleanup and don't seem to have any ill effects on the scale itself. One gripe though: the weighing platform is only about 10 cm square so anything larger than a small coffee cup will block part of the digital displays. After all, the scale needs to fit inside an espresso machine. It isn't a full size kitchen scale.
But really, do you need this device? If you want to be ultra precise in your coffee measurements, you love gadgets, or you revel in the coffee making ritual, the answer is certainly YES!
