I use it for making ESPRESSO. The accuracy of 0.1 grams is absolutely sufficient. The same applies to the weighing capacity (up to half a kilo). An important feature that I like about the product (always in comparison to low-cost scales) is that it has an immediate response to small changes in weight.
Obviously, at such a low price, it is not waterproof. But I use it just fine for weighing liquid coffee. The purchase cost is so low that buying a scale 20 times more expensive doesn't make sense (in my opinion).
In coffee preparation, a deviation of up to 0.2 grams in the beans, and up to 1 or 2 grams in the liquid coffee does not affect the result at all. There is no need to spend more on a precision scale for making coffee.
