Today I received it, from the first impression I like it, it is large in size, heavy, sturdy, I downloaded the software and set it up, I like that I was able to set copy-paste on the side buttons, over time I will comment again on performance and durability.. so, after 2 weeks of use... I removed 2 stars because the scroll wheel is inconsistent, it is not stable, the image moves up and down while I scroll down, very annoying for a mouse of this price range... one star, not even a year of use and the cursor on the screen was flickering.. wasted money

I have chosen it for everyday use at work for many years, I have not found anything better! It is the perfect size and weight, and with a curve that fits the human hand, so it is comfortable without straining the wrist, unlike the various ones usually recommended for laptops. Also, the scroll wheel has the option of either slow scrolling or free scrolling, which is incredibly convenient.
The only negative is that the scroll wheel is noisy and after years it starts to break. Despite that, I highly recommend it!

Initially, it worked fine. After a few months of not very intense use (not for gaming, only office use), it started malfunctioning. Double-clicking all the time, the cursor jumping to different points on the screen, etc. I thought maybe it was due to some stupid driver update. I went to the Logitech website and downloaded the latest drivers for Windows 10 64-bit, but it was the same. It's a shame because it's pretty good in other aspects. At home, I have a Sharkoon Shark Force that I've used extensively for both gaming and office work, and it doesn't have any issues, and it costs less than half the price. I'll probably get the same one for the office.

It is not as sturdy in construction as mentioned in other reviews.
Expensive for its quality.

The buttons have the feeling of a mouse that you have had for some years and they have started to wear out.

Also, sometimes you wonder if you pressed the left click or not.

The middle button of the scroll wheel usually needs 2-3 firm presses to work.

I have had it for a decade and it hasn't had any issues. Sometimes, however, the left button, also known as the click, doesn't work. It's understandable after ten years.

Well, my mouse for years with only "infidelity" the wireless brother of the marathon (which broke after 5 years and I will buy it again). I don't change it, my friend, no matter what happens, flawless in everything and I can no longer live without the free rolling of the scroll wheel. Note! If you want it to work properly, you have to set the Logitech setpoint otherwise it's like having a different mouse!

It has 6 buttons:
- the 2 usual buttons for right and left click
- 2 side buttons to go forward and backward in browser pages
- 1 button below the scroll wheel that changes the scrolling mode of the wheel
- the scroll wheel itself as a button, opens a hyperlink in a new tab

I find it very comfortable (weight, design, cable length). Unfortunately, it doesn't have durability over time. I bought it on 01/12/2017 (€35.5). On 11/10/2018, it suddenly stopped working and was replaced. On 08/07/2020, the left click button started malfunctioning (doesn't bounce back after pressing). I managed to fix it by following the video below:

Time will tell how much longer it will last.

I give it one star only because the cable seems very simple and cheap, which makes me afraid that it might break easily. It doesn't have any sleeve and it's not particularly thick. Also, when shaking the mouse quickly, you can hear the scroll wheel hitting the two buttons. It seems like it doesn't fit well in its place. Other than that, the mouse is very decent for its price. Personally, I chose it because I wanted a mouse under 30 euros with two side buttons and a free-roll on the scroll wheel for quickly scrolling through text pages.

We are talking about a Logitech product that means reliability. It has a free-rolling scroll wheel if you press the button below the wheel, personally I don't use it.

It is a bit heavier than it looks and gives the feeling of Quality when you carry it in your hand.

Personally, I use it on Mac OS system, Windows 10 Pro, and Chrome OS. I have had no problems for 1 year.

The previous Logitech mouse I had lasted me 10 years.

After 7 years of intensive office use, I chose the same mouse again. Very good fit in the _right_ hand. Keys with ideal feedback and a strong click, but not annoying. I highly recommend it.

It has two options for the wheel, one silent but in this setting the wheel "runs too much", the other has a mechanical and strong sound. Comfortable mouse in the hand except for the sound.

In general, it is a nice mouse, very comfortable in the hand, especially if you have a larger hand and most mice seem annoying to you.

I had 2 of these in the last 6 years, and both had a problem with the right click after 3 years, when the warranty expired. Also, the rubber on the sides is comfortable, but over time it wears out and develops indentations where the fingers press. The rubber can also stain the fingers a little in the summer.

Overall, it's worth its money if you can find it cheap.

At first, I can say that this mouse amazed me, but as time went by, the mouse simply stopped working, which is a shame because I bought it for about 40 euros, and when you click the left button, it automatically double-clicks and you can't use it properly. Sometimes it's completely useless, which is a shame because I have bought many products from this company and I have never had any issues. What can I say, did I just happen to get a faulty one?

In two words:
I use it at the office. Incredible ease of quick scrolling through documents the size of a thesis. The use of the side forward backward buttons is a lifesaver for navigating through intricate paths of documents.. (those who have worked with clusters where the server "cuts off" paths due to excessive length understand..)
Without much ado, it makes my work higher quality and more comfortable. I have never used anything better.

It is inconceivable dear Logitech, a mouse that was bought three years ago for 60€ not to work well, to lag at random times, and even to "eat brains". Today I bought a Philips optical mouse for 4€ from Stournaris which works just fine.

-If it breaks in 3 months
-I will replace it with the same one for 4€.

Why should I prefer you again, just because you have the name Logitech?

Durable and with a nice grip. One of the best mice I have ever bought for everyday use. In terms of durability and grip, there is no significant difference compared to my previous MX Revolution. The only downside is that after 4 years of owning it, the plastic parts, especially on the left and right sides where the thumb rests, have worn out quite a bit.

It is very good in handling, even in gaming, it responds very well compared to more expensive mice. I highly recommend it!

-It is a very good mouse.
-For gaming, I only play Strategy games on PC and it suits me perfectly. I don't know how it would look on a demanding PC Gamer.
-I use it for internet browsing and various programs like Word, Excel, Photoshop, Mathematica, etc.
-I have had it for about 1.5 years and it hasn't had any issues.
-After that, it depends on what each person is looking for. From how it feels in your hand to how many shortcut keys you want it to have and other various things.
-Personally, I have only changed a total of 5 mice (including this one) in the 16-17 years I have had a PC, and it is the best one I have gotten so far for my needs.

+ : Good quality/price, large size, works on many surfaces, free-scrolling, side buttons.
- : It is quite heavy and does not have very good accuracy. The scroll wheel makes a lot of noise when not in free-scrolling mode, and the middle button is not easy to press.

I bought it because I prefer wired and the M105 that I had before was too small for the size of my hand. It has a good feel and fit in the hand, the side buttons are user-friendly, it is durable and overall does its job. It has a small issue in my opinion with the scroll wheel and scrolling on pages, but pressing the middle button somewhat fixes it. As for gaming, I don't think this particular mouse without DPI can perform accurately, especially in games that require precision. Personally, I didn't buy it for gaming and I am satisfied with it for the past week that I have had it. As user gg234gg mentioned, download Logitech's setpoint for better settings, disable Windows, and you'll be fine.

Simple and reliable. However, it requires some adjustments to show its true self.

Disable acceleration from Windows and install Logitech's Intellipoint (disable any acceleration from there as well). Note that Logitech's software does not need to run constantly in the background once the settings are saved. You can completely disable the software in the startup tab of the Task Manager.

I like it because it resembles the G502 in shape and its scroll wheel is flawless. It simply does its job for gaming. However, for office use (Excel, PowerPoint), it is perfect. If you like its shape and weight, go for it. It's worth its money. After using it for a year, it still feels brand new.

Very good mouse, excellent for its price. I have had it for 3 months and I am completely satisfied. It fits well in the hand, the side buttons are user-friendly, it doesn't tire and it is quite accurate. It works very well with Macs.

I have had this mouse for about 1 and a half months! I did not expect it to perform so well in gaming! It fits perfectly in my hands (slim, medium size) and its weight is sufficient (for those who prefer heavy mice) to be sturdy and precise in every movement. The feature of the scroll wheel with infinite scroll is good if you want to scroll down a lot on a page and you're lazy. :P You just give it a scroll and it goes dooooown! Buy it without fear!

The best mouse I have ever tried. It fits perfectly in the hand, the side buttons are user-friendly, and it doesn't tire you out. I have one at home and I want to buy a second one for the office. I wish it also came in wireless

One of the best mice for everyday office use. Of course, there are better ones for gaming (with greater precision), but for desktop use, it is top-notch.
