Where we land on it A dosing cup that weighs, in Tritan with an invisible display and USB-C — and the only scale on this shelf that publishes neither a precision nor a capacity. At the top of the shelf by price, that is a remarkable omission.
What the maker puts in writing
Dosing cup with integrated scale
400 mAh battery, USB-C rechargeable
IPX-4 splash resistant
Tritan body, food safe, hot or cold
Hidden LED display, capacitive touch
The two numbers that are missing
A scale is defined by how finely it reads and how much it will take. This listing gives neither.
Seven other products on this shelf publish 0.1 g (0.004 oz). Six publish a capacity. The cheapest of them costs under a third of this, and tells you both.
What it is good at instead
It is a cup. Grind into it, weigh in it, tip it into the portafilter, rinse it. That is a real workflow and nothing else here does it.
Just be clear about the trade: you are buying the form, and the specification sheet is somewhere else on this shelf.

What it gets right, and wrong
Strengths
The only product on this shelf that is a dosing cup and a scale at once, which removes a transfer step from grinding
An IPX-4 rating, the only ingress figure published anywhere on this shelf
Tritan rather than glass or ABS, stated as safe for hot espresso and cold brew alike
Compromises
Publishes no weighing precision and no maximum capacity — the two numbers that define a scale — at the highest price here
No timer at all, where six scales on this shelf have one
A dosing cup is not a platform: it will not sit under a drip tray and weigh a shot
Where this one stands among its neighbors

What people want to know
How precise is it?
The listing does not say, and neither does it give a maximum capacity. At least seven of the twelve scales on this shelf publish 0.1 g (0.004 oz), and six publish a capacity between 750 and 3,000 grams. This one publishes a battery size and a plastic grade instead.
Can I weigh a shot with it?
Not in any usual way: it is a cup, not a flat platform, so it does not go under a portafilter on a drip tray. Five scales on this shelf publish their dimensions precisely because fitting under a machine is the question.
What is it actually for?
Weighing a dose of beans in the vessel you then tip into the grinder, and weighing the grounds that come back. It removes a bowl from the bench. On this shelf nothing else does that job — and nothing else leaves out the precision either.

2 kg (4.4 lb) × 0.1 g (0.004 oz) · 6 modes · water resistant
The one scale here built to survive a drip tray. Six modes, auto-start timers and a silicone cover — which addresses the thing that actually kills coffee scales.
Best for: Espresso on a wet drip tray, which is where scales go to die.
