Firstly, for its price, it is definitely worth it.
Secondly, it does its job wonderfully.
Thirdly, I agree that cleaning it is difficult and you have to do it very carefully to avoid getting water into the device.
Lastly, the lid on top holds coffee for a short period of time

It does its job well at a good price. I would like a slightly larger container that was also detachable for easy emptying in the coffee maker and cleaning, however, for its price, it does its job well and I recommend it.

To cut a satisfactory amount of coffee, you put the coffee in the lid (upside down, that is). No problem so far, I have purchased two pieces. I recommend it easily.

Good for its price, but I bought a Gaggia grinder, of a different category, and I realized that the key to espresso, at least, is the grinding mill. Different coffee, similar to a café's result, even with a simple machine.

For its price, it's good. It does its job (espresso) if you don't mind the fact that it doesn't have a container to collect the coffee and you have to turn the whole grinder upside down to get it out, resulting in the complaint of the woman because you have filled the kitchen counter with coffee powder. Otherwise, 15-25 seconds of grinding and you're ready. It holds about 1.5-2 doses of coffee at a time. And yes, the lid gets foggy, but after a certain point, you only realize if it's ready by the noise. If you have extra money, get something more practical, but this one does its job.

We have been using it for two years for espresso and spices. It takes a minute or two to grind the coffee finely, it is very noisy, and it is difficult to remove the coffee from inside. We don't have a comparison with another product, only with professional ones! It has not presented any problems so far

I have it for two weeks now. I believe it does its job just fine for its price. It looks qualitative, but be careful with its lid, it might fall and break. It doesn't seem very sturdy. For grinding, it requires a little practice and constantly checking its interior to achieve the desired grind that you prefer. However, it grinds espresso coffee quite finely if you want.

A decent quality product but... Blade grinders, as I have found out, do not produce fine enough powder for espresso! You can make it, but the quality is noticeably low. And if you grind for a long time to make the powder fine, the coffee gets heated, sticks, and loses its aroma, and I say this without being an expert in coffee. After a few days of use, I did some more research and decided that for better results, one needs to get a grinder with a conical shape. So if you want a strong aromatic espresso and not, let's say, filter coffee, it's better to go straight for something specifically designed for this task. In the end, this here is essentially a small blender...

The device is excellent. It cuts the espresso easily and very quickly. For a household machine, it is exactly what is needed.

Good construction.
It cuts the espresso for finely ground coffee in about 15-20 seconds.
It is worth its money and more.

Sturdy construction, simple operation with just one button. Personally, I prefer that not everything is automatic and I can also participate in the way the coffee is ground. Imagine that if you want it finely ground, you simply hold the button down firmly, while if you don't want it to be finely ground, then you can pulse the button to grind it as much as you want. I wonder how I used to enjoy coffee that wasn't freshly ground! A different aroma!
