Corsair M65 RGB Ultra Tunable Gaming Mouse

Would give it a 5, but for my needs, I deduct one star for productivity. For gaming, this is excellent. However, when I use this all day for work, the buttons are so sensitive that I find I can’t just rest my hand on the mouse for long reading sessions. I end up mouse clicking unintentionally. Usually, this isn’t such a big deal as it just opens contexts menus and such. Also, the Icue software interface is more difficult to navigate and understand than the logitech gaming software I used before. Icue is very powerful, and all sorts of adjustments are there, but it requires some reading and getting used to. Overall great high quality mouse that’ll take your gaming to the next level.

1 WEEK UPDATE: After a week of use I have decided to return this mouse and try the Ironclaw. The bottom line is, I am not getting used to the feel of this mouse. I think it is just too small for my hand. I also don’t like the sniper button being located where my thumb naturally rests. Sometimes I pick up my mouse to re-position it and I end up pushing the sniper button sometimes. There is no question that this mouse is superb as a dedicated gaming mouse. Between the 26,000 DPI capability and the 8,000 Hz polling rate, this thing really performs as a gaming mouse. But for everything else, it falls short for me. I want a larger mouse that is more oriented towards comfort, I am willing to trade off some of the gaming performance to have a more comfortable mouse.

Original Review:
For the past 5 years I have been using the Corsair Sabre and just recently noticed issues with the right click, I was having to push it harder for it to stay on during gaming. Other than that it still works fine so I will keep it as a backup mouse. But I decided to upgrade to the M65 RGB Ultra. Last two photos are comparisons of the M65 vs the Sabre. As you can see the size of the two is equivalent, but the shape and feel is very different.

1. With all the weights installed, the M65 is significantly heavier. With them removed, significantly lighter. So it is very nicely tunable in the weight department. I am keeping all of them installed as I like a heavy mouse.
2. For pretty much everyone the sniper button on the M65 is going to be located where your thumb naturally rests on the mouse. This is one of the biggest differences that requires getting used to. The button requires a firm press to activate so accidentally doing so really isn’t a concern. Its just the feel of the button constantly on your thumb is different if you have never used a mouse with a button in this location. FYI in default setup pressing the sniper button (at any time) changes the mouse to the sniper DPI setting (400 DPI), this is really nice to have during gaming. I don’t play a lot of FPS games but I will still use it occasionally. Of course you can program all the buttons to do whatever you want them to do in iCue.
3. The mouse wheel on the M65 has a grippier feel and is much harder to rotate. It also has a very solid click into place. It isn’t a smooth scrolling wheel, it has very pronounced ‘notches’. Some will like it, some won’t.
4. I have the wired version and the quality of the USB cable is excellent and very soft. The USB plug itself has grippy rubber on it and is also very well made.
5. The range of DPI with this mouse is crazy. I tried 26,000 DPI but frankly I don’t see how anyone would ever use it, even in FPS games. I changed my settings from 1200 DPI to 15,000 DPI and even then I will probably never use the 15k setting. The most I ever use in game is about 12k. But it is still available if you want it.
6. One of the draws of the wired version of this mouse is the 8,000 Hz polling rate. I just tried it while playing the Dead Space remake and did NOT like it at all. It felt unnatural to me. It was so fast that I was getting rapid and unexpected movement in game that went away when I lowered the setting to 4,000 Hz. At 4,000 Hz it is still extremely responsive and feels much more natural to me. I suspect that I am probably so used to having a slight delay that it just feels more normal. Note that it also requires a lot of CPU power to function in game at 8,000 Hz. Its not worth it to me and I didn’t like it, but to each his own.

Overall I am happy with this mouse. I still have to get used to the overall feel of it in my hand, but that will happen fairly quickly. Hopefully it holds up.

The Corsair M65 Gaming mouse exceeded my expectations in every aspect. Its precision and responsiveness during gameplay are truly remarkable, thanks to the advanced sensor and customizable DPI settings. The sniper button is a game-changer, providing on-the-fly sensitivity adjustments for those critical moments.

The robust construction with aircraft-grade aluminum not only gives it a premium feel but also assures me of its durability. Comfort is key during long gaming sessions, and the ergonomic design of the M65 ensures that my hand feels at ease.

The customizable RGB lighting adds a cool aesthetic touch, and the programmable buttons offer a personalized gaming experience. Setting up and customizing the mouse through Corsair’s software is a breeze, making it user-friendly.

In summary, the Corsair M65 is a fantastic investment for any gamer looking for a high-performance, durable, and stylish gaming mouse. It has definitely elevated my gaming experience, and I wholeheartedly recommend it to fellow enthusiasts.

I just got the M65 RGB Ultra Wireless in today along with a K100 RGB Keyboard. So far my impression of the mouse is meh… Ergonomically it’s a much smaller mouse than I am used to and it sits far forward in your hand almost to the point to where it feels like it is going to shoot forward from your grip. My biggest issue however, is the left click vs the right click. The left click feels stiff and gives a hard click when pressed which is both felt and audible. The right click feels how a mouse click should feel, smooth, tactile, and little resistance with a quiet click. Ultimately I’m going to be sending this mouse back after having researched the issue and it appears to be a repeated and ongoing issue for quite some time. To the extent that they address the issue and provide a “solve” on Corsair’s website which simply offers how to reset the mouse… which surprise, doesn’t fix the issue! Pretty bummed because I was really excited to use this mouse side by side with my new keyboard which so far is pretty epic!

I have this one and the wired version and I love it for gaming and everyday PC use, I have zero complaints, I have normal man sized hands not small not large and it fits well, no hand cramps, It’s not covered in buttons so prob not for the types the like hotbuttons which I do not.

Size and weight are good for me, software allows many changes – but not able to disable the sniper button.
