Corsair’s M65 is an FPS (first-person shooter) icon on the earth of gaming mice. After seven years and a number of iterations, Corsair has proven that the M65 design isn’t going anyplace. The M65 RGB Extremely Wi-fi is one thing new, although. It’s the primary time the design has gone wi-fi, and at a value the vary has by no means seen earlier than.

Though the M65 has by no means been a finances choice, the primary wi-fi variant pushes up the worth to just about twice that of the wired model, lastly nudging the mouse over the $100 mark.

Nonetheless, the M65’s comfy design and tunable weight system make it an awesome decide for critical FPS gamers.

Corsair has made some model of the M65 because it launched in 2014. And for probably the most half, the design has stayed the identical. It’s a tall, stubby mouse with a pronounced bump within the again that feels excellent for palm and claw grip. I exploit palm grip, and the M65 Extremely Wi-fi offers me simply sufficient to carry onto.

Like earlier variations, this one is constructed with an aluminum body that lends a way of heft to the mouse. In contrast to the earlier Elite model, the M65 Extremely Wi-fi comes with a textured floor on each side, just like Corsair’s Darkish Professional RGB. I like the addition, because it brings only a hair of grip to an in any other case matte design.

Whereas 18 grams could not sound like a lot, it makes a world of distinction.

Similar to its wired counterpart, the M65 Extremely Wi-fi comes with six removeable weights. They’re break up into three sections, so you may select to have the interior weight, the exterior weight, each, or neither. Along with shifting the load from 110 grams as much as 128 grams, the weights are additionally distributed to regulate the middle of gravity.

Whereas 18 grams could not sound like a lot, it makes a world of distinction. The M65 Extremely Wi-fi is a heavy mouse to start with, particularly with all the weights in. There’s numerous room for adjustment right here, so long as you want a heavy mouse (one thing just like the Razer Orochi V2 is healthier in order for you a lighter choice).

The burden makes the M65 Extremely Wi-fi really feel like a unit, too. In case you’ve used any of the previous M65 iterations, you already know what I’m speaking about. This can be a hefty mouse that looks like it might stand as much as strain, not like numerous ultralight esports mice that really feel like they’ll fly away in case you don’t grip them tightly sufficient.

Nonetheless, it’s essential to acknowledge that the load isn’t for everybody. Though the M65 has adjustable weight, it’s heavy regardless, similar to the Logitech G502 Hero with its removeable weights. The M65 Extremely Wi-fi is heavier than the wired M65 Elite, too, by 13 grams (although lighter than M65 Professional by 5 grams).

Sensor and buttons

The M65 Extremely Wi-fi comes with eight programmable buttons, which is ideal for me. It’s a few extra buttons than the Corsair Sabre Professional Wi-fi, however nonetheless fewer than an MMO behemoth just like the Logitech G600. Along with left- and right-click, you’ve gotten entry to ahead and again thumb buttons, up and down DPI adjustment, and the thumb sniper button that’s iconic to the M65 vary.

For the left- and right-click, Corsair is utilizing Omron’s optical switches, not like the mechanical switches you’d discover on most mice (together with the M65 Professional and M65 Elite). There’s numerous minutia with why optical switches are higher than mechanical ones, however it comes right down to delay. Principally, a mechanical swap has a small quantity of “debounce delay” between whenever you press it and when it reaches its reset level.

Optical switches don’t have that drawback. They use mild as a substitute of a bodily swap, which eliminates debounce delay. All informed, this delay is so small that most individuals gained’t ever discover it. Nonetheless, optical switches are technically quicker, so in case you want a sanity verify that somebody in Valorant truly killed you, the M65 Extremely Wi-fi affords one.

It’s the texture of the optical swap that has me hung up.  There are only some mice with optical switches — particularly the SteelSeries Prime and Razer Basilisk V3 — so I’d suggest making an attempt one in every of them in-store earlier than choosing up the M65 Extremely Wi-fi. It isn’t a nasty feeling, however optical switches don’t provide the identical click on as a mechanical swap — it’s nearly as if there’s a dampener.

Apart from a swap improve, the M65 Extremely Wi-fi comes with a sensor improve. It options the 26Okay DPI Marksman sensor, similar to the Corsair Sabre Professional Wi-fi. That’s above even the 25.6K DPI sensor on the Logitech G Professional X. Just like the optical switches, a better DPI sensor is technically extra correct even when it’s not related for most individuals.

The two,000Hz polling fee is related. Shifting from 1,000Hz — which is typical of wi-fi gaming mice — to 2,000Hz cuts down the response time to 0.5ms. From the buttons to the sensor to the polling fee, the M65 Extremely Wi-fi is ready as much as provide you with a bonus, regardless of how small.

Connectivity and battery life

Just like the Corsair Sabre Professional Wi-fi, the M65 Extremely Wi-fi comes with Bluetooth and Corsair’s Slipstream wi-fi know-how. You’ll be able to toggle between them on the underside of the mouse, which I discovered myself doing usually, swapping over to a house theater setup with the M65 and my Logitech G915 TKL.

The M65 Extremely Wi-fi affords precisely what I’m searching for in a wi-fi gaming mouse.

With none lighting, Corsair claims as much as 120 hours of battery life when utilizing Bluetooth (90 hours when utilizing Slipstream). The mouse routinely sleeps after 15 minutes, nonetheless, so you may fairly use the M65 for weeks with out a cost. In comparison with my Razer Viper Final, I didn’t really feel the charging bug almost as usually. And after I did, the USB-C port for charging meant I used to be hardly ever with out a spare cable.

The M65 Extremely Wi-fi affords precisely what I’m searching for in a wi-fi gaming mouse. Fast switching between 2.4GHz wi-fi and Bluetooth makes the mouse versatile for various setups, and the battery lasts lengthy sufficient to by no means really feel like a problem. USB-C is a giant win, too, not like mice just like the Razer Viper Final which might be caught with a micro USB port.

Software program

Corsair’s iCue software program is a motive to choose up the M65 Extremely Wi-fi. Like Logitech’s G Hub and Razer’s Chroma, you may customise the RGB lighting and alter button assignments in iCue, together with mapping absurd macro features to any of the buttons. After you have all the pieces set, you may retailer your DPI, lighting, and macro profile on the mouse to make use of it freed from iCue.

There isn’t a lot in the way in which of lighting, with the M65 Extremely Wi-fi sporting a single zone for the emblem on the again. Nonetheless, iCue lets you entry customized lighting results like rain or a temperature sensor. I’m keen on static lighting throughout my rig, which iCue segments right into a separate, simplified part.

Essentially the most intriguing a part of iCue with the M65 Extremely Wi-fi is the gyroscope. The six-axis gyroscope lets you configure liftoff detection, however it additionally opens up the likelihood for gestures. The M65 Extremely Wi-fi consists of ahead, again, left, and proper tilt gestures, which you’ll map to any key or macro similar to a traditional button.

And to my shock, it really works. I don’t think about I’ll ever use the lean operate — instantly after setting it up, I accidently despatched the mouse right into a frenzy after flipping it the other way up — however it works. There are some makes use of for it, too, like utilizing Alt + Tab to cycle by home windows or mapping a key like PrintScreen that you will have to hunt for in any other case.

Corsair’s iCue is a necessary a part of the M65 Extremely Wi-fi. It goes far past buttons and lighting, permitting you to entry to distinctive options like gestures and significant settings like when the mouse goes to sleep.

Our take

The Corsair M65 Extremely Wi-fi squarely targets two different mice — the Logitech G Professional and Razer Viper Final. The Viper Final is about $20 costlier, whereas the M65 and G Professional are each $130. Efficiency-wise, there isn’t a giant distinction between these three mice, so it comes right down to options and desire.

Corsair’s mouse has a couple of perks on that entrance. The optical switches are quicker, it features a large battery, and it comes with USB-C for charging. I like the design and really feel of the M65 as properly, although numerous that comes down at hand dimension and the way you maintain your mouse.

I’d have favored a barely cheaper value — round $110 just like the Sabre Professional Wi-fi — however the M65 nonetheless feels a step forward of the competitors.

Are there any alternate options?

Sure, a number of. For top-end, wi-fi FPS mice, the Razer Viper Final, Logitech G Professional X Superlight, and Corsair Sabre Professional Wi-fi are all choices.

It can save you large with a wire, too. Corsair’s wired M65 is $60 cheaper, and there are alternatives just like the SteelSeries Rival three for round $30.

How lengthy will it final?

Omron optical switches don’t include the identical 50 million-click life span because the mechanical ones. Most optical switches last more than mechanical ones, although. The M65 Extremely Wi-fi ought to final 15 years or extra, long gone whenever you’ll in all probability need to swap to one thing new.

Must you purchase it?

Sure. The M65 Extremely Wi-fi is a wonderful wi-fi gaming mouse. It comes with the identical premium options as related mice just like the Razer Viper Final and Logitech G Professional X Superlight.
