I bought it used in 2022 for 50 euros and as I saw the other day, the one I have was manufactured in 2019, so it has been working for almost 7 years now.

I don't have much to say.

I use it daily for 8+ hours at the office and I have it connected to my laptop via Bluetooth. It has not disconnected even once.

It is extremely comfortable, it also has a side scroll wheel which greatly helps with navigating technical manuals and websites, while at the same time it is particularly sturdy (and heavy, of course).

As for the battery, whatever one says is not enough: I literally charge it once every 2-3 months, and that's after practically 7 years of use.

The only thing that has happened is that the rubber covering the body has developed some bubbles (as shown in the photos) but apart from aesthetic reasons, it doesn't bother me at all in use.

Personally, out of all the mice I have tried, I consider it No.1 for professional use. By far.

Build quality is excellent. It withstands falls... tested multiple times. Perfect for professional use. It has many functions and meets all requirements. No issues with connectivity to any computer. Still looks new after 2 years. And the battery easily lasts a month.

The only negative is its weight. You can't really call it lightweight

I bought it almost when it was first released and so far I have had no complaints.
Its battery is truly a beast and with just one charge and a lot of use it lasts for over a month. Lately, it's been acting up (the pointer freezes, loses connection, etc.).
I will keep it until the next one comes out.

It did not suit me due to its weight. The little finger, as I hold it, is relatively in the air and bothers me. Otherwise, its wheels are incredible and overall it is an excellent mouse for someone who holds it well in their hand.

I bought it from a major retailer in Athens for 90€ on sale. I had the MX 2S and I think this one is better in every aspect. If someone liked the MX 2S, then this is an upgrade at least in terms of quality because the software is the same with the same problems.

- Many buttons on the mouse for someone to do anything
- Per application configuration (e.g. the scroll wheel to do different things in Word and Excel)
- The scroll wheel is 10 times better than before and silent
- The buttons make a little noise but I don't care
- Excellent build quality
- Excellent battery (charges via USB-C)
- You can charge and work at the same time
- Ergonomic
- Not suitable for small hands, or go to a major retailer (e.g. Kotsovolos) to try it out
- Overall, I find the button placement very convenient
- DPI for my needs (computer programming and some gaming) is excellent

Personally, I consider it one of the best mice for its price, especially if you find it close to 100€.

The good: It has almost every function you could ask for from a mouse and it is incredibly comfortable to hold. It charges quickly, lasts a long time, and does not hinder you from using it while it charges.

The bad: The material absorbs every trace of dust and dirt it comes into contact with, especially the back and side where your hand rests. After 1.5 years of use, it has become like jelly. I have tried cleaning it with everything, from plain water and a cloth to "special" plastic cleaning products. Nothing saves it. It costs so much money and for someone who uses it daily, it will only last 2-3 years. Other mice that cost 20-30 euros last the same amount of time, if not longer, but they are also 20-30 euros.

Conclusion: You pay 100-120 euros more than the average mouse to have 3-4 extra buttons and a scroll wheel that moves sideways. In terms of build quality, you will get the same, if not worse, compared to something that costs 20-30 euros.

Simple things:

Positives:

Good weight
Decent dpi
Good software support
Design
Durability
Battery life

Negatives or areas for improvement:

Noise from the keys, which has been fixed in the new version that I have tried
Ergonomics. Although there is an ergonomic series for this reason, I would like to see a version with a small call on the side

These are all my conclusions as a owner since 10/21.

Very good. If you get used to it, you can't change it. Many functions, accuracy, long battery life

The mouse is very comfortable for long hours of work. However, I bought it in gray and after 5 months of use, it appears dirty with yellow lines and it doesn't clean at all. If I had known this from the beginning, I wouldn't have bought it.

I use it every day due to work for 8+ hours. Really no complaints, the battery lasts so long that you forget when you last charged it, switching from one laptop to another is simply done with the press of a button, very comfortable in hand.
The only negative thing I could point out is that if you work with a pen, pencils, etc., the gray version gets easily dirty and is difficult to clean.

It has a nice feel in the hand and is comfortable and sturdy. In my opinion, its strong point is the scroll, having been disappointed in the past by the Logitech G402 and G502, which are of course intended for a different use. The connectivity is excellent and it doesn't lag anywhere. For now, I like it, it will show if it's worth its money in the long run.

Ergonomic and incredibly convenient in the hand, with a slight tilt to the right for the hand to sit more naturally and a large space for the thumb (where it also has a button). Wireless and rechargeable, so you don't have to deal with cables and batteries. No issues with connectivity, immediate response of hand movement to cursor. The buttons have the characteristic "click" that I prefer in a mouse. The main scroll wheel scrolls in increments, and with the press of a button it becomes smooth. It also has a second scroll wheel that scrolls only smoothly and allows for horizontal scrolling (personally, I set it for volume adjustment). All buttons are adjustable, aiding productivity. The best mouse ever! I highly recommend it!

Edit: (13/06/2023)
I just learned that if you press one of the side buttons while scrolling, you can also control the zoom on the screen (similarly, like pressing Ctrl on the keyboard and scrolling). I am extremely satisfied!

Perfect. It works perfectly. I use it for editing with Final Cut, if you customize the shortcuts, it's an awesome tool.

It is very good and expensive.
I use it for professional purposes.
The accompanying program (Logi Options+) makes the mouse highly customizable.
The infinity scroll is a lifesaver when searching through large folders.
Its design is very good and it fits my entire palm.
The battery life is amazing (I have only charged it once since September).
Initially, I had it on an XXL mouse pad and it didn't glide as much as I would have liked (note that my entire palm is on the mouse and my wrist does not touch the mouse pad). As soon as I removed the mouse pad, it is much better.

Excellent, high-quality, and the right size. Also, the battery life is very good. In addition, the fact that it can be connected to three different devices simply by changing a switch underneath is a plus. And finally, you can control 2 computers with one mouse using the program provided by Logi.

The only negative thing for me is that the Logitech software is not compatible with Linux. Other than that, it is a pleasure to have this mouse in your hand and the convenience it provides

Ideal in touch for long hours of use in the office, fully ergonomic and customizable, worth its money!

I will not write a long review or upload photos, as there are many others who have excellent reviews. I will just say a few words about the mouse and whether it is value for money. But one might wonder, is it possible for a mouse to be worth almost 100€?

Yes, my friend, it is if:
1) you won't miss that money for basic needs
2) you have a medium to large hand and work for over 8 hours.

First of all, it is a gem. The mouse embraces the hand and is comfortable. Hand pains from cheap mice are gone. The customization options are very convenient, especially if you work with multiple pages/data. The scrolling is very comfortable, maybe that's the main reason why the hand pains disappeared. After using it for 2 days, you won't want to use any other mouse. The only concern is its durability, especially with clicks and scrolling, and I'm talking about after the warranty period.

Who it is NOT for:
Women/children/men with small hands and fingers
For gaming

I will write a detailed report since I have many years of experience with this mouse.

JUST GET IT

k bye.

Excellent mouse. Endless battery life. I use it with an iMac M1 and in my opinion, it is far superior to Apple's Magic Mouse. Comfortable in hand, many buttons, very good scroll, fast and easy pairing. The negative for me is that the click on the buttons sounds quite loud (I think they have fixed this in the MX Master 3S). Although expensive, its quality is evident and it is worth the money

It is simply perfect. I recommend it to anyone who wants an ergonomic mouse for long hours of work and productivity.

The best mouse I have ever used in every aspect.
-The battery lasts a long time, I haven't measured exactly but maybe I have charged it 3 or 4 times in 6 months.
-The Logitech software is very good and programming for gestures is easy.
I have nothing negative to say, except that now, with all the other mice, I feel that something is not right. For someone who will work in front of a screen, it is the best choice.

Excellent and clearly improved compared to the old Mx I had. It is simply a pleasure to work with it. The presets for various applications are very convenient - I wouldn't have thought of them myself.

I often use Excel and software in general with frequent use of the scroll (e.g. multi-page PDFs, Word, etc.). It is expensive, but after using it, you won't go back to mice that don't have their own scroll. I also have the MX Anywhere 3. Equally good as well!

I had an Apple mouse and now I tried this one. For long hours of professional use, there is no discussion, it is much better. First of all, ergonomics, you work comfortably. There are no wrong movements from the touch. If you forget to charge it, there is no problem, it charges while it works as shown in the photo.

Nice mouse, with many functions if you install the Logitech software.
I have had it for a month and I haven't charged it yet, so its battery is durable and lasts a long time.
It can connect to 3 devices and switch by pressing a button under the mouse.
Overall, if you work with multiple devices remotely, it's worth its money.
It's even good for gaming.

Very good construction and good ergonomics with good customization of the keys through the application and good battery life. The only negative (hence the 4 stars) is the Bluetooth connectivity that disconnects many times, and this is due to Windows 11 from what I understand! Maybe with the USB Dongle, this issue won't exist.

I bought it on 3/11 and until today, 22/11, it lasted with one charge. I use it for about 10-12 hours a day and I never turn it off because I'm lazy, so overall I have to say that its battery lasts quite a long time. As for the feel in the hand, when I first received it, I wanted to return it immediately because it didn't fit my hand at all (I used to have a gaming mouse). However, after a day or two of getting used to it, I have to say that now gaming mice don't suit me anymore. It feels completely different in the hand. Overall, it seems to be a quality build, the buttons are nice, and both the scroll wheels are useful. I would recommend it.
