This mouse works amazing. Even in wireless mode I can hardly feel any delay in game.

Great mouse, fast and accurate, it’s also perfect for large wide hands.

Like the mouse y very good and beatificación the lighs

The M65 design has been a mainstay for Corsair’s mid-to-high end mouse for a long while now. The design is simple, and to the point. Well suited for FPS and RPG/RTS alike. This latest M65 RGB Ultra brings some of the best features of Corsair’s other high end mice, along with some very unique switches for the buttons to this excellent design. If you’ve used any previous M65 this mouse will feel instantly familiar. I own a wired M65 RGB Pro from 4 or so years ago and the design is extremely similar. Compared to that mouse, the M65 Ultra has better button placement and textures. Overall it looks and feels the same, but more refined. If you have any of Corsair's recent wireless mice, the experience is quite similar. The slipstream wireless dongle is small and capable. The mouse itself also pairs with bluetooth, making it easy to use it with your gaming PC and iPad. There is a small switch on the bottom to swap modes. One of the more unique features of the mouse is the optical omron switches. These switches feel so nice and smooth. They differ from the normal clicking switch you find in other mice (most high end use omron). They use a beam of light to determine when the switch has been pressed. Having lost some great mice to bouncing (double clicking) switches, these seem like a boon. How they’ll last long term will be the real question. Another unique feature I’ve not seen in previous M65 (or corsair mice in general) is gestures. The mouse can detect tilt and can trigger a key press or macro when tilted. I tried this in CS:GO to map a right tilt to “R” for reloading. I actually found that quite natural to use. I however did find that activating that profile and not setting it as a general profile is probably the way to go. Again iCue gives you tons of options here, but it was funny to type the letter R just by lifting and rotating the mouse. Like all Corsair mice with RGB in the name, the M65 RGB Ultra has a single zone of lighting. I’m glad to see they didn’t overdo it here. Obviously it can be synced with the rest of your corsair accessories or disabled to increase battery life. Speaking of battery life, so far I’ve been impressed. While this doesn’t offer the Qi wireless charging like some of Corsair’s mice (probably due to the aluminum frame), it seems to get great battery life. I haven’t had to worry about charging it yet and it still has over 75% battery life. It does come with a USB-C to A cable, and yet another device that can charge over USB-C - yay! Unlike the M65 of yesteryear, the aluminum frame on this M65 is more of a natural aluminum color. I like this flair - and the toning down of some other plastic gamery flair. It honestly makes it feel more grown up. Beyond that, the scroll wheel and non-primary buttons feel good. I believe the primary buttons are the only optical switches, because the other buttons feel quite similar to the M65 wired I have. The sensor is excellent. The Marksman 26k - which according to research is a rebranded Pixart 3393, is an amazing sensor. Corsair didn’t skimp on this mouse. This mouse is geared to be an FPS mouse, with its responsive sensor, well defined scroll wheel and sniper button (which changes the DPI to a higher setting on the fly by default). But obviously this makes a great all around mouse as well. One feature that’s not unique, but is part of the M65 DNA is the adjustable weights. You can add or remove 3 weights to change the mouse’s overall weight. While the adjustment is only about 20 grams, you can feel the difference. Some people like more weight, but if you’re like me, the lighter the better. Still at 110g this isn’t the lightest mouse to start with - however I would assume most people would adjust well. Overall there’s a lot to like about the M65 RGB Ultra. It’s a refined and upgraded version of an already excellent mouse. It feels great in the hand, and button placement is improved from earlier versions. Beyond that it combines an excellent sensor and what should be a very durable switch to keep this mouse gaming for years to come. I’m impressed and excited by this mouse.

nice balanced mouse good for fps games and easy to use

I bought this mouse and within the first month the wireless dongle stopped working. Spoke with Corsair CS and they sent me a replacement mouse. After a year, the wireless portion stopped working so I had to switch to Bluetooth since it was now out of warranty. After a few months of that the Bluetooth stopped working. Troubleshooting did not work. Now I have it plugged into my computer using it as a wired mouse despite paying for a wireless mouse. Probably will have to get a new mouse soon. In summary, don't buy this.

Despite updating firmware, intermittently lags during gameplay and misreads/skips surface detection. Works better using usb 2.0 than 3.1, but still experience the delays and skips.

Very smooth functionality. Worth the buy for gamers.

Love this little mouse that could. The snipe button on the side is pretty useful!

This is amazing. It works really good. I would recommend

Left mouse button will some times stop working, resulting in poor performance. Solution is to turn off mouse hold both left and right mouse buttons down and power on mouse again.

At random time this mouse does not stay connected to my pc. Also mouse 4 and 5 buttons do not work. But feels sturdy. This is why i give this mouse a 3 out of 5 stars.

Awesome product! Exactly what I was looking for! Works perfectly!

EZ to manage!! EZ to drive!! Great tool for delicate work...

Replaces a previous m65 model that died after 6 years of hard use.

Awesome mouse! Compliments my Corsair keyboard and desktop!
