Peculiar
At first thought, it seemed great to get a good estimate of the grind particle size. In reality, the correct usage is a bit of a mystery. The manufacturers guide you to carry the ruler alongside the coffee and visually assess the grain size - similar to a toothpaste tube's whiteness meter, except the eye is good at distinguishing shades, but not at detecting small size differences. Another issue arises from the fact that the grind is full of particles of various shapes and sizes, making it very difficult to estimate the true size.
It's also possible to try to sprinkle the grind through the slots, but such panning for gold doesn't work very well, as the particles are of different shapes and sizes, so they mostly just sit on top of the slots. Some finer particles go through, some remain hanging by a sharp corner.
In summary, one might think this tool would be handy and useful, as well as simply an interesting gadget. In reality, using it is a mystery and it doesn't provide any better data than what you could assess with the naked eye as "now it's quite fine/coarse" or "finer/coarser than on another setting". Especially not worth its price; if you measured its usefulness and implementation, this would be worth 2-5 euros, not 20 euros. You can get an ordinary ruler from a store like Tiimari and keep it next to your grind and assess just as well.
It is what it is
It does what it's supposed to, neither more nor less.
I'm not entirely sure how useful it actually is, as it involves quite a bit of guessing after all.
