  1. Atty

    This mouse is super ergonomic! I love the feel of it and the lighting while visible is still super low-key. The optional weights that it comes with help give it a more stable feel, but without them the mouse is super lightweight and is crazy quick. I would 100% buy this again if I needed a new mouse

  2. Zaúl Padilla González

    The previous models were great, but this one R even better. Does mouse with good feels and right amount of buttons

    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.

    This is a great wireless mouse, the buttons feel tactile and great with fast response times. It’s adjustable weights work well for those who want different weights from the base weight of the mouse, it’s rgb is great and is bright and it’s built in adjustable dpi helps with getting a better feel than non-adjustable mouses. The battery life is great and lasts a while with constant use. I’ve had it for a month or so and I’ve only had to charge it twice. The side buttons and sniper button are great for gaming and web browsing. All buttons on the mouse are customizable and the ique software works great and isn’t hard to use. Overall a great mouse. I would highly recommend picking this mouse up and other Corsair products.

    Es muy cómodo, se nota enseguida la calidad de los materiales y el agarre del mouse, cambié del Corsair Glaive a este y ambos han sido de lo mejor que tenido en cuanto a mouse, súper satisfecho con la compra, 100% recomendado

    It’s a really good mouse, but not as ergonomic as the previous design of the m65, there is a tendency to press the thumb trigger button while gripping the mouse. Software is great.

    The clicks are very plasticy, the weighted screws on the bottom can only be tightened by hand, if you use a screwdriver itll dent the metal of the screw causing burrs to stick off the bottom of the mouse.

    Coming from a Corsair Scimitar, this mouse is slightly heavier with all the weights applied and much lighter without the weights. The clicks feel disappointingly cheap compared to the Scimitar.

    This mouse comes with a function where you can program different commands for when you tilt the mouse, this does not work well. For example I set on Back Tilt to open chrome. Whenever the mouse would move it’d open a new window in chrome. I picked up the mouse and out it down as you would do moving around a wide desktop, and it opened like 50 windows of chrome.

    It does come with a wireless feature, but only has 90-120 hours of battery life, which if you work from home or leave your computer on sleep often the battery life is more like 4-5 days. Might as well leave it wired.

    Otherwise it looks great.

    I bought this mouse because I have had hand issues with other mouse styles. I have used the wired version for years with my desktop so obviously I like it. This wireless one is for my laptop and it works flawlessly. Not a fan of all the RGB stuff but I set it to stay on one color which I like. I like not having the wire. I charge it in between uses and so far the battery life is great.

    I like m65 rgb ultra wireless mouse cos comfortable to hold and feel. I dislike mouse the left click getting very light while clicking after sometime

    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.

    Nice weight adjustable gp mouse. Bought to replace an Office R.A.T. that I had repaired and had finally crapped out. Entirely adequate for my needs.
