In general, an honest and quality mouse, with a sturdy construction that has nothing to envy in features, compared to more expensive wired models of other companies. I would prefer it to be a little cheaper, but at 50-60€, what it offers is hard to find in the same price range. If it is found at an even lower price during sales, it is a choice with closed eyes.

Its main advantages are the very good optical sensor that reaches up to 18,000 dpi, the omron switches, its low weight, the flexible paracord cable, and the option for native 8,000Hz hyper-polling (which of course requires a modern and relatively capable PC to work).
It also has great customization in its settings and in the three-zone lighting (scroll wheel, back logo, dpi mode indicator on the side), through Corsair's I-Cue program.

As for the disadvantages, first of all, the I-Cue, despite the great customization it offers, remains a relatively heavy and cumbersome program in its menus, which requires some searching to adjust everything to your liking, but unfortunately this applies to all Corsair products it supports. An issue I noticed (without being a deal breaker though) is that both click buttons have a very light play left-right. Nothing tragic, but because in general it seems to be quite quality and sturdy, this small detail slightly diminishes the overall experience and creates second thoughts about whether the play will increase over time and after use.

Finally, I would like to mention that in general, it is a large mouse designed for right-handers, so check its dimensions and compare them with what you already use to see if it will suit you. For medium-large male hands that prefer palm or claw grip, it is marginally okay and the side buttons sit very well under the thumb. For smaller hands, female or children's hands, it may not have the ideal fitment. Nevertheless, for its size, it is incredibly light and user-friendly.

To me the mouse sat right in my hand and I liked its shape and weight, although at first touch it felt a bit strange. It is a large mouse, so it is suitable for medium to large hands. My hand is 19x9 cm without the thumb. If you have smaller hands than this size, I would suggest trying it before buying it. Its clicks are the most immediate I have ever seen in my life (if you don't want them as immediate, you can learn more about the mouse by watching the review by Rocket Jump Ninja). The icue reaches 1 GB and has customization settings that I believe are better than any other application, but it can be chaotic and requires some exploration. Also, don't get fooled by the 8000hz, even YouTubers don't know if there are games that support it, maybe in the future. Don't believe that you will find the perfect mouse, especially today when they are not made with the same quality as 5-6 years ago. The mouse is made of lightweight plastic and weighs 70 grams, and it is not meant for heavy use, just like any other mouse I have tried, including the Razer V2. It is perfect for gaming, with great accuracy and responsiveness, nice clicks, and a cord that feels like it's not even there. The RGB lights are the brightest out there, so be careful not to blind yourself and keep the rage to a minimum. I hope I helped. I will get back to you for anything else.

I come from HyperX Pulsfire (the first in the series that came out - 5 years of use) and Razer Mamba Elite, which had a broken scroll wheel after 1.5 years of use exactly. So, with the warranty of the second one, I decided to try something slightly different.

I have been using it for 1 week now, and I can say that I am impressed by its large size, proper weight, and the feeling of its scroll wheel. I haven't been using it for gaming much in the past 2 years (less than 8 hours per week), but due to the nature of my work, I spend a lot of hours on the computer. I have relatively large palms for a male hand, and it has been incredibly convenient for me!

I will come back to add more information as I get to know better what this mouse has to offer.

Update 25/4/2023 (8 months of use): At the price of 60 euros that I got it from the warranty of the previous mouse, I don't know if I would buy it, it was borderline worth it or not. Especially now, at the current price of 70+ euros, it is not worth it at all. It's a good mouse so far, but it's really overpriced at the moment. Add it to your cart only if it drops to 50-60 euros. For that price, it should have more buttons, more RGB, and a more polished software than the iCUE, which randomly closes on Windows 11.

The Sabre RGB Pro Champion Series for FPS/MOBA games may not catch anyone's eye, but it's the technology hidden beneath the surface that makes the difference! This particular mouse features a powerful sensor, durable switches, Quickstrike buttons with zero gap, up to 8,000Hz hyper-polling rate, and of course, on-the-fly DPI adjustment with LED indication.

Equipped with six buttons: left and right click, scroll wheel, forward and backward buttons on the left side of the mouse, and the DPI switch located behind the scroll wheel. The RGB lighting is located on the company logo and the scroll wheel, which can be customized through the iCUE software.

On the bottom surface, there are four PTFE glide pads that minimize friction on surfaces. The glide pads can be replaced with others upon request, as there are no replacements included in the packaging.

Settings
On the left side of the mouse, there are three LED strips that indicate which of the five preset DPI settings you are on (400/800/1200/1600/3200). The five levels can be modified from 100 to 18,000 DPI with precision unit through iCUE. The sensitivity can also be changed on-the-fly by 50 DPI, simply by holding down the corresponding DPI adjustment button and using the forward/backward buttons on the left side of the mouse (forward to increase DPI by 50 and backward to decrease by 50). There is also a Reset option for DPI by simultaneously holding down the three DPI buttons - forward/backward. As a bonus, one of the six buttons can be assigned as a sniper button.

The ease of on-the-fly DPI customization is definitely a key feature for demanding gamers.

Dimensions
The dimensions of the mouse are 129 length x 70 width x 43 millimeters height. Like the price, the size places it in the mid-range category, neither large nor small. However, its weight is considered small relative to its dimensions, as it does not exceed 71 grams (without the cable). Ergonomically, regardless of the preferred grip style, it offers a comfortable hold and is recommended by Corsair for use by palm or fingertip users.

Switches & Scroll Wheel
The durable OMRON switches can withstand 50 million clicks. Good luck counting them! The Corsair Quickstrike buttons use springs and a type of hinge that eliminates any gap, providing intense and faster clicks with reduced travel distance.

The scroll wheel has a good feel and appears sturdy in its construction. It has a slightly heavy feel, but unfortunately, you cannot adjust this part to make it spin more easily.

Optical Sensor
Inside, we find the PixArt PMW3392 optical sensor, which is a surprise considering the mouse's price. Its maximum sensitivity reaches 18,000 DPI, while its tracking speed reaches 450/0.125 inches per second. One of the top advantages of the Sabre RGB Pro is its polling rate, with a value of 8,000Hz. With Corsair's AXON hyper-processing technology, this mouse has 8 times the transfer speed of clicks and movement on your PC compared to conventional mice. The highest reference rate reduces minor delay appearances and leads to faster, smoother movement.
Polling Rate Needs
Upgrading the speed from the 1000Hz that most market mice have to the 8000Hz of the Sabre RGB Pro does not have a significant impact, meaning there is no significant difference in usage. However, for a professional or highly demanding amateur gamer, the 8000Hz may be helpful.
The maximum polling rate of 8000Hz burdens the system, so there is a corresponding notification when you select it. Corsair recommends using the Sabre RGB Pro with at least an AMD Ryzen 7 2700-Series or Intel Core i7 9700-Series CPU. Similarly, for use at 4000Hz, an AMD Ryzen 5 2500-Series or Intel Core i5 9400-Series CPU is recommended. To avoid misunderstandings, the mouse works on a less powerful system but will not be able to perform at its maximum, while on Mac computers and Xbox One, the polling rate does not exceed 1000Hz. Personally, I tested it on a Ryzen 9 3900x and did not notice any performance issues with the system (that was missing).
Cable
The connection cable is 2.1 meters long, covered with parachute-style paracord. It is flexible, pliable, and lightweight. Just be careful with the integrated Velcro cable tie as it can damage the woven paracord surface when the scratch comes into contact with it.
iCUE Software
If not all, most Corsair products use iCUE, the company's application. You will need to spend some time getting familiar with the application and modifying any settings since despite the changes made to the application, it continues to be complex, mainly due to the many options it offers. Defining one of the six buttons as a sniper button, switching the RGB lighting, defining DPI levels and polling rate allow you to customize the mouse to your liking. Through iCUE, you can calibrate the mouse according to the surface you have and save the lighting settings as well as the functions you have programmed for the buttons in its memory.
Lift off Distance
The Saber RGB Pro does not have predefined LOD levels, but manual surface calibration is provided through iCUE. Using the default calibration, the sensor periodically checks only at the height of a CD. It is understood that the LOD varies slightly depending on the surface used.
Conclusion
Usually, anything that uses the term gaming is relatively unapproachable in terms of price and complexity, both in design and use. The Sabre RGB Pro mouse, aimed at esports professionals, has a price that will not force you to take out a loan to acquire it, and due to its simple and elegant design with a dose of Scandinavian-Japanese minimalism, you do not need to have space-themed colorful peripherals to match it with your space.
All players-users will appreciate the ability to on-the-fly adjust the DPI of the excellent PixArt sensor, as well as the extreme 8000Hz polling rate. Its design and size provide the desired ergonomics, while Corsair has equipped it with high-quality OMRON buttons with 50M clicks and glides that slide comfortably on good surfaces at least. Additionally, the scroll wheel has a good feel, although it is somewhat heavy and cannot be adjusted to have a lighter feel, unfortunately.

Perfect perfect perfect! I bought this particular mouse because it's not RGB and it's 5 grams lighter than its color sibling. Only 68 grams. It's the first time I have such a lightweight mouse and I'm amazed.

Besides being very lightweight, it's also big. It has a similar shape to the Deathadder, I would say, but this one has more curves on the right and left.

Also, the clicks are very addictive, soft, and responsive. They have a system that eliminates pre and post travel distance. So you can spam comfortably without getting tired.

Lastly, 8000hz. Okay, they went all out. I have activated it but I notice that my PC struggles a bit more. I haven't seen any difference in responsiveness and I will probably leave it at 2000. Maybe if you're a pro player, you will notice a difference with the 8000hz polling rate.

(By the way, let me explain what polling rate is. Essentially, 1000hz means that the CPU checks if you have given any command - mouse movement every 1ms, 500hz every 2ms, and 250hz every 4ms. Now imagine at 8000hz. It checks every 0.25ms!)
