Slightly Inaccurate but Works Well
Pros:
Works perfectly for what I need it for. I use an aeropress and it's super easy to weigh the coffee going in and then the water on top of that. Then start the timer for the brew time and you've got a beautiful cup of coffee! Very bright display, easy to read, and comes with a rubber pad which makes cleanup easy.
Cons:
Not super accurate, but it's fine for making coffee unless you want to be exact. Sometimes the tare doesn't hold perfectly. For example, put your coffee on the scale. Tare it. Take it off. Put it back on. It might read a tenth of a gram or so one way or the other. Never impacted my coffee routine...

Been working well for over a year
Had this for over a year now and no real issues. The only issue I can think of is that if something is a bit too close to the scale, the scale can fluctuate a bit by a gram or so. Just make sure nothing is touching it, especially anything electronic.
Beyond that, it's a no-nonsense scale that works great with actual tactile buttons. Its refresh rate can lag behind a tiny bit, but you get used to it by stopping your pours in anticipation. For example, I typically do 300mL pours in total, and I usually start slowing down/stopping at around 280g. Battery life is pretty good, but the battery life indicator doesn't do a good job of letting you know when you need to replace the batteries. So you may end up with it powering off mid-brew, but I've only had to replace the batteries once despite daily use over the past year or so. That being said, it's useful to also do stuff like the 4:6 method based on water level vs timer too.
I'd also say it may not be extremely accurate as sometimes it fluctuates by .1 grams, but it is accurate enough for practical purposes. For reference, .1g is simply ~1 coffee bean, and unless you're an espresso perfectionist, 1 coffee bean isn't going to make any real difference.
In summary:
+ Just the essentials if you only want the essentials
+ Tactile buttons
+ Display is pretty nice
+ Accurate enough for practical purposes
+ Battery life very good
+ Will work for at least a year, can't say any longer until I own it for longer
+ Great for the cost
= WIll not refresh weight as quickly as say an acacia scale which costs at least four times as much, easy to compensate for
- Battery life indicator isn't great, so it may power off mid-brew every half year or so
- Sensitive to adjacent electronic devices, 1 or 2 inches is enough distance
- Sensitive to adjacent objects, be mindful of anything that is touching the silicone, even if it's barely touching by a hair

Works Perfectly, Ignore "Drift" Reviews
Color: Onyx Black, Color: Onyx Black
I'm very happy with the accuracy and refresh rate of the scale. The two tone LED color scheme is a nice touch. I also like that the silicone cover is well-affixed to the scale and won't slide around. I only wish the scale came in white!
Don't be fooled by other reviews. This scale doesn't "drift" any more or less than any other scale. Those people who say otherwise are likely storing it in a very different temperature environment than their use area. See photos for the test I did with boiling hot water in an uninsulated carafe. 0.0g drift on all tests, with or without the silicone protector, after several minutes of letting the carafe sit on the scale surface.
The only time I experienced measurement drift was when I got the package from 30F freezing outdoor conditions, unboxed it and tried it out without letting the scale warm up to ambient. The measured weight slowly dropped until it warmed up to 70F room temp; since then it's been rock solid. That is totally normal for any scale that any manufacturer, cheap or expensive, makes. It's just how this kind of scale works.
Overall if you're looking for a nice scale with timer functionality, I highly recommend the Greater Goods scale.
