The Corsair Glaive RGB Pro is a medium to large gaming mouse made for right-handed users who prefer using their mice with a palm grip. It's most likely best with hands bigger than 17 cm, which is as always also a matter of personal preference. The mouse has not one, but three different left side panels you can swap between, held in place by magnets. This is definitely a great feature and makes the mouse suitable for a much wider variety of users.

Surface and materials are fantastic on this device; the main parts feature a soft-touch matte coating, which feels very nice in the hands, although it does collect fingerprints quite easily. All side panels feature some textured rubberization, which is great with maintaining a stable and firm grip even when the situation gets sweaty.

Build quality is well above average. This mouse doesn't squeak, although it can emit quiet creaking sounds when the shell is being tortured with great force. There are no rattling parts, and everything is aligned well both inside and out. Weight-wise, the rodent is already lighter than its predecessors, but at 112 grams, it could still lose a few more grams in my opinion, which is mostly a matter of personal preference, though.

Buttons are great on the Glaive, which is another improvement since the last iteration. The main ones pretty much have no unnecessary travel and feel nice and tactile. Their Omron switches are rated for 50 million clicks. Scrolling has average resistance and lots of tactility, so it's great for precise actions as well as browsing. The middle click is a tad too stiff for my taste, although not as bad as on the previously reviewed Ironclaw RGB Wireless; thankfully, all other buttons are all relatively light and without any issued.

Sensor performance is fantastic once you turn off all the RGB lighting. Unfortunately, the frequency of the LEDs interferes with the sensor, and it periodically drops polls, causing instability in the tracking. This is most probably easily fixable with a future firmware update I really hope Corsair will soon deliver. Without lighting enabled, the PixArt PMW3391 works as intended; it provides raw, ultra-responsive tracking without any unwanted acceleration or angle snapping and has a ridiculously high perfect control speed. It has the usual smoothing on and above 2100 CPI, so for competitive gaming, it's best used below that resolution.

The feet are among the better ones for sure; they are smooth and consistent without any scraping and have a medium to low friction. Their contact points are well rounded; however, there are no replacement sets included, which is kind of a letdown at almost $70. The cable is essentially the same as on most other Corsair mice, which is bad news since it's very stiff, thick, and heavy, resulting in a lot of resistance and friction. However, it's definitely a durable cord.

Corsair's iCUE software is a medium to heavyweight all-in-one suite for their newer devices. It's well made, but could be simplified and organized better in some sections, though I found it to be intuitive and usable. I didn't detect any bugs while using it, either. If you don't like it installed, you can simply remove the program after setting the mouse up since it has on-board memory that can store all settings. RGB lighting—while it causes problems with performance—is great on the Glaive RGB Pro (hence its name). There are three lighting zones that can light up individually, and a vast amount of effects and customization options you can fiddle around with are available.

The debut price for this mouse is $69.99, which is fair if you consider its specifications, but such harsh firmware-level errors as in this case should not be allowed. I'm sure Corsair will roll out a fix in a firmware update very soon, and given this mouse is near-perfect objectively otherwise, I'm happy to recommend it. If you find the shape and specifications appealing, the Glaive RGB Pro can be an ideal choice for casual use and serious gaming.
