I have it here for 10 months.
So, in terms of grip.
Lightweight and well-designed (for my hand, of course!!!) it doesn't tire you even after many hours of use, 12-14 hours. 8/10
100-8000DPI and with many settings for them. 10/10
Nice sound in the click (for me) it is quite loud.
Fully adjustable RGB Lighting since you can adjust each LED separately, rare for this price, and the LEDs seem to have high brightness and, most importantly, quality colors that will last. 9/10
Build quality.
Okay, although it seems to be of good quality, it is plastic.
Fabric cable.
The color has not faded.
Electrical durability has not shown any issues in the 13 months I have it.
Now, durability against drops, hits, punches, etc., I don't know.
I respect the money I spend, so I don't mishandle it. 10/10, always with a reservation as time will tell.
Software.
At first, it is a bit complicated, although it offers many options. 4/10
In conclusion, for me, I believe that there is no competitor at this price, even at double the price, so I consider it a very good and economical choice.

Purchased for 23.37 euros. Okay, it's not playing around.
First of all, it is very good in terms of ergonomics, even though ambidextrous mice usually have issues in this area. Its shape is correct and you don't accidentally press clicks even with a large palm. The side buttons are easily accessible only with the thumb.
The sensor is from Bloody, I think, but it is not from Pixart. However, it has the same "sharp" and immediate feel, without any "skipping," at least so far. It doesn't have any drifting in any DPI setting (used on a fabric mousepad). The mouse feet are made of aluminum!
Finally, it is COMPLETELY silent during scroll wheel movement (it has regular "steps"), with just the right resistance, pleasantly impressive.

The software allows for DPI adjustment and button click delay (in milliseconds). Additionally, the company frequently releases updates (unfortunately, you have to check it yourself, as it doesn't have auto-update yet) and solves various issues that may arise (mainly after major Windows updates).

10 buttons fully customizable, RGB presets with the ability to program your own effects, 160kb internal memory to store settings, polling rate up to 2000Hz, max 8000dpi adjustable and independent per axis if desired (very useful for Ultra wide screens), and generally everything you need... it has. And even the things you don't need... it has those too. And optical switches on the main buttons (let's not forget that it's a patent of Bloody that Razer copied). For the money, it's like stealing from the company.

It doesn't have weight adjustment. If that doesn't bother you, get it with your eyes closed.

P.S. For aspiring Minecraft players, I should inform you that it doesn't do drag clicking.
