The wheel does its own thing. It broke after a few months of use. I had Logitech for years, but the last two mice I bought were both faulty.

I have had it for 4 years (since June 2020). I use it as my main mouse daily (typical use and design programs) and I frequently use the scroll wheel click.
I disagree with what I read about the material and cleaning. I use it CONTINUOUSLY and outside the house, it has never shown to be dirty, nor does it require frequent cleaning.
The only thing, after 4 years, is that the coating material of the scroll wheel has started to wear down at one point on the edge, which I do not perceive by touch, only if I look at it closely.
However: it does not have a silent click, personally it does not bother me, but I must mention it.

Very good response and stability in movement. I had bought 3 mice but they were a bit cheaper and I threw them away.

Guys, the mouse is very mediocre.
1. It needs constant cleaning due to its material.
2. After 1 year of use, it has started to stick several times and doesn't move no matter what you do.
3. It easily scratches (due to the material) on the back, BUT someone has to sit and observe them.
So it's not a mouse that you will have for a long time... however, overall it is good, quiet, good size, nice grip on the sides, but always be careful not to drop or hit it because it doesn't seem so durable against impacts.
Oh, also it needs to be very close to its USB otherwise it doesn't work at all

The only negative thing (hence the 4 stars) is that after about a year of use, the wheel stopped scrolling smoothly and requires extra force to work. It also requires special attention as it collects dirt on the sides due to the material and construction, and needs regular cleaning to look nice. Other than that, it's very nice and I believe it's worth its money (it was purchased for 16-17 euros in 2019 and is still being used as the main mouse for the laptop).

This particular mouse is good for its price. It is medium-sized.
It is easy to use.
Durable when dropped from a common desk distance.
The only negatives are that the keys make noise, so if you pay attention to it, they will annoy you.
And the second negative is that after 2 hours of use, my wrist got tired due to the size of the mouse.

Once it fell from the bookshelf and the axle of the wheel inside broke. I had to open it to see if I could fix it and I noticed that it is made of plastic. Where you apply the most force and if it falls (upside down) it protrudes and will break. !!!!!!!!!!

It is a very good mouse, I'm just not sure if it is well constructed. However, I can say that if you shake it abruptly, you will notice a slight creaking, so it may be due to its construction or the wire that gives the commands.

Positives:

Nice design
A brand that inspires trust (I have several Logitech products, from cheap to expensive, and they are all worth their money).
Very good grip in the hand, the thumb fits perfectly.

Negatives:
Somewhat small, I have a medium-sized palm and it hugs it more than I would like.
A bit heavy, which is understandable considering it has a battery inside.
The distance from the USB adapter needs to be short (less than 30 centimeters) otherwise it occasionally loses contact and seems to "glitch".
It easily gets dirty at the thumb area as it has small holes to prevent slipping (which works), but they easily collect dust/dirt.

Overall, a good mouse. I have been using it daily at work for 2 months and it hasn't had any issues, although I had to change the battery only once.

For its price, it is decent. It lacks the extra buttons, but if you only need a mouse for desktop, it's fine.

For the money, it is very good with good responsiveness. The batteries last quite a long time for light gaming, and it is good and reliable. It has fallen several times without any damage. Great value for money

For its price and size, it is just what you need! Convenient size for a laptop bag and decent battery life. The only drawback is that it is quite noisy... But with this price, you overlook it.

It is very good for its price, just be careful not to drop it because it easily breaks. Other than that, it is very reliable for someone who wants a good mouse

When you press the left click multiple times, you can hear the spring from the inside and it's frustrating when it breaks. Other than that, the size doesn't suit me but that's my preference. Overall, it's good but it's likely that if I had to buy again, I would go for something better.

I had it for 2 years of daily use, about 10 hours a day, and suddenly it broke.
It's worth it for being invisible optic.
The plastic is cheap and the wheel has worn out after 2 years of use.

For the first two weeks of use, the mouse is flawless! Lightweight, responds to movements accurately, quiet clicks... so far, a very good purchase!

It is good for 18€. Cheap plastic of course with a good feel in the hand. Immortal battery! Generally easy to use and probably the best for this price. Finally, it is small in size, a little bigger than a mini, which doesn't suit me as I have large palms.

Medium-sized mouse, low and pleasant sound in clicking and scrolling. Beautiful design and definitely a very good choice for its price (20€).

Ergonomic design with very nice textured details on the sides. High-quality construction and immediate response. Nothing fantastic, but at 20 euros, one of the best choices.

+ Battery life, good response (even on "difficult" surfaces).
- Noisy (even the scroll wheel & button), excessive "plastic" feeling, collects a lot of - and visible - dirt (at least in blue color).
