The main left/right switches are made by Omron and use light rather than metal contact to trigger, for lower latency and faster actuation. The mouse features eight well-placed programmable buttons, including a big dedicated sniper button on the left to drop your DPI down for those precise headshots. If you’ve never used or owned one of the previous M65 iterations before, the M65 RGB Ultra is a medium-sized mouse (which I find perfect for my medium-sized hands), that is 117 mm front to back, 77 mm wide at its widest, and 39 mm tall. Personally, I like the mouse at its lightest, but it’s nice to have options. Three sections on the bottom screw off, revealing weights that can be added to or removed, letting you adjust the rodent’s weight between 97 and 111 grams as well as adjusting its center of gravity.

Like previous models, the M64 RGB Ultra also has an adjustable weight system. I didn’t find this to make any difference in gameplay, but it certainly looks more natural. These are subtle changes, but they're helpful - especially during long gaming sessions or during the summer when even the AC can’t keep your claw hand cool.Ĭorsair has also moved the mounting area for the cable from its previous position, a bit off to the left on the front of the Pro mouse, to the center on the newest Ultra model. The new M65 RGB Ultra has textured sides and a similar finish on the rubberized scroll wheel. The older mouse (top right in the image above) had smooth sides and a modestly textured scroll wheel. 5.08 x 2.76 x 1.69 inches (117.0 x 77.0 x 39.0 mm)Įxterior Design of the Corsair M65 RGB UltraĬorsair also made a couple of appreciated exterior changes over the previous 2019-era M65 Pro RGB.
