Such a device came into my hands, with the problem that it didn't cut well. I tried various hacks, I even raised the lower blade to make it cut better.
But the solution was in the next video

Now it works perfectly with all settings, and if you adjust the upper blade even lower, it cuts almost like dust!!!

Let me start by saying that I bought it for €110 on Black Friday, but I will judge it based on its regular price.
It is not stepless, but it has enough steps, so I believe that it would be difficult for someone not to find the desired grind size. It can go very fine, so it is great for espresso.
It is well-built, sturdy, almost all stainless steel.

At the bottom, it has a drawer for disposing of the coffee grounds, personally, it doesn't suit me, so I have turned it into a compartment for a scale, tamper, etc.
The only 'complaint' is the retention it has. If you use it as a single dose, it's a little issue.
So, either you have the patience and clean it every time, or you discard the first 2-3 grams that come out because they are the ones that remain in the grinder from the last use.
Overall, to get something better, we are definitely talking about €300+ euros, so this one is value for money.

The container at the base for the coffee grounds is difficult to use because it requires cleaning every now and then and a little bit... I bought it on Black Friday for 119 euros and it is worth the money.

I have it for 3 days and I'm still experimenting with how finely I can grind the coffee. At the finest setting, it's almost like grinding Greek coffee into powder. It retains a bit of coffee inside when grinding, but it doesn't bother me as I use it frequently. I got it for 114 euros on Cyber Monday and for that price, it's definitely worth it.

I have no words... I can't drink coffee outside anymore. Everyone seems tasteless to me now.

I have tried several types of coffee and different grind sizes. I have settled on 15 for the grind size (without adjusting the grinder) and Passalacqua Harem coffee, which gives excellent results with the equipment I have.

Update 18.11.23: It still works perfectly, it hasn't stopped working for even a day. Just to give you an idea, I took it with me on vacation during the summer. In the end, I have settled on Lo'r coffee. It's a great balance between quality and price, and occasionally I also enjoy a Passalacqua.

1. The house smells amazing.
2. Finally, an excellent foam is made with a non-pressurized basket.
3. To achieve the above, you need to remove the grinder. Unscrew it from the back by pressing a button, unscrew two screws on the inner ring and turn it 3 holes to the left, then screw it back in for a finer grind. Then adjust from the outer ring. Mine was set well at 30.
4. To prevent coffee from remaining between the grinder and the container, simply use the container's spout. Open it, coffee falls into the grinder, close it, grind... that's about one dose. Repeat for a second dose (the professional 58mm basket requires 2 doses). This way, no coffee remains to oxidize and spoil.
5. It is beautifully designed with stainless steel and at a very good price (I bought it for 116 euros).
6. I heard about the difference the grinder makes and I thought it was an exaggeration. I was proven wrong.
