Pleasant surface
Seamless connection to PC
Nice backlight
Silent clicking of the main buttons. The side buttons and scroll wheel click louder.
Because of the bevel on the wrist side, the hand is not on the pad but on the bevelled part of the mouse. After an hour of work, my arm was aching. But maybe it just didn't fit my shape. However, I will be returning it because I bought it so my arm wouldn't hurt.

After a few years, my mouse from the same brand went away. I was quite happy with it, so I decided to try the more "modern" one again from Eternico.
I was slightly disappointed after unpacking it, because it looks quite cheap for the price. The original mouse seems to me to be a better quality plastic.
The "main buttons" are quiet, the scroll wheel is too, but when pressing the scroll wheel and the buttons on the side they are loud like the old mouse (classic click). The scroll wheel is so sensitive to pressure that I quite often get an accidental press when scrolling.
I don't know if it's my piece, but sometimes it "gets stuck" - the LED lights up that the mouse is connected, but it doesn't work on the PC, so I have to turn it off and on.
The battery life seems to me much weaker than the original one, it lasted me more than a month. This new one I have to charge it once a week.
I positively evaluate the size of the mouse. I have an unusually large hand and long fingers for a woman, this one fits my hand perfectly.
The backlight is unnecessary for me, but it's a "fancy" detail. There are a few preset options to choose from.
This is not the mouse's fault, but my bad choice. I wanted it to match the rest of my PC, so I chose white, which I now consider a bad choice. She's pretty dirty in a few days. Thanks to the coating, there are stains on it, for example from a pen, which cannot be removed.
