RRP $ 130.00

"The Corsair M65 RGB Ultra is the latest gaming technology in an iconic design."

advantages

  • Blunt, comfortable design

  • Optical mouse switches

  • Tilt gestures

  • 26K DPI sensor

disadvantage

  • Expensive compared to the wired version

  • Much heavier than other high-end mice

Corsair's M65 is an FPS (first person shooter) icon in the world of gaming mice. After seven years and several iterations, Corsair has shown that the M65 design is going nowhere. However, the M65 RGB Ultra Wireless is something new. It's the first time the design is wireless, and at a price that the range has never seen before.

While the M65 was never a budget option, the first wireless variant pushes the price down to almost double the wired version and eventually pushes the mouse over the $ 100 mark.

Still, the M65's comfortable design and tunable weight system make it a great choice for the serious FPS player.

Corsair has made a few versions of the M65 since its introduction in 2014. And the design has mostly stayed the same. It's a large, stocky mouse with a pronounced bump on its back that's perfect for palm and claw gripping. I use the palm grip and the M65 Ultra Wireless gives me just enough to hold on to.

Like previous versions, this one is equipped with an aluminum frame that gives the mouse a feeling of weight. In contrast to the previous Elite version, the M65 Ultra Wireless has a surface structured on both sides, similar to Corsair's Dark Pro RGB. I love the addition as it just adds a touch of grip to an otherwise matte design.

Even if 18 grams doesn't sound like a lot, it makes a big difference.

Just like its wired counterpart, the M65 Ultra Wireless comes with six removable weights. They are divided into three sections so you can choose to have internal weight, external weight, both, or neither. In addition to shifting weight from 110 grams to 128 grams, the weights are also distributed to adjust the center of gravity.

Even if 18 grams doesn't sound like a lot, it makes a big difference. The M65 Ultra Wireless is a heavy mouse to begin with, especially with all of the weights. There's a lot of scope for customization here, as long as you like a heavy mouse (something like the Razer Orochi V2 is better if you have a lighter variant).

The weight of the M65 Ultra Wireless also makes it feel like a unit. If you've used any of the last few iterations of the M65 you already know what I'm talking about. This is a beefy mouse that can withstand the pressure, unlike many ultra-light esport mice that feel like they'll fly away if you don't hold them tight enough.

Still, it's important to realize that weight isn't for everyone. Although the M65 has an adjustable weight, it's still heavy, just like the Logitech G502 Hero with its detachable weights. The M65 Ultra Wireless is also 13 grams heavier than the wired M65 Elite (although it's five grams lighter than the M65 Pro).

Sensor and buttons

The M65 Ultra Wireless comes with eight programmable buttons, which for me is perfect. It's a few more buttons than the Corsair Saber Pro Wireless, but still fewer than an MMO giant like the Logitech G600. In addition to left and right click, you have access to the forward and backward thumb buttons, up and down DPI adjustment, and the thumb sniper button, iconic for the M65 range.

For left and right click, Corsair uses Omron's optical switches, as opposed to the mechanical switches you'll find on most mice (including the M65 Pro and M65 Elite). There are many details as to why optical switches are better than mechanical, but it comes down to the delay. Basically, a mechanical switch has a small “debounce delay” between being pressed and reaching its reset point.

Optical switches do not have this problem. They use light instead of a physical switch, which avoids debounce delays. All in all, the delay is so small that most people will never notice it. However, optical switches are technically faster. So if you need a health checkup who actually killed you from someone in Valorant, the M65 Ultra Wireless has one.

It's the feel of the optical switch that got me hung up. There are few mice with optical switches – namely the SteelSeries Prime and the Razer Basilisk V3 – so I'd recommend trying one of these in the store before picking up the M65 Ultra Wireless. It's not a bad feeling, but optical switches don't provide the same click as a mechanical switch – it's almost like there's a damper.

In addition to a switch upgrade, the M65 Ultra Wireless comes with a sensor upgrade. It features the 26K DPI Marksman sensor, just like the Corsair Saber Pro Wireless. That's even above the 25.6K DPI sensor on the Logitech G Pro X. As with the optical switches, a higher DPI sensor is technically more accurate, even if it's not relevant to most people.

The query rate of 2,000 Hz is relevant. The change from 1,000 Hz – typical for wireless gaming mice – to 2,000 Hz reduces the response time to 0.5 ms. From the buttons to the sensor to the polling rate, the M65 Ultra Wireless is designed to give you even the smallest edge.

Connectivity and battery life

Like the Corsair Saber Pro Wireless, the M65 Ultra Wireless also features Bluetooth and Corsair's wireless slipstream technology. You can switch between them at the bottom of the mouse, which I did a lot when switching to a home theater setup with the M65 and my Logitech G915 TKL.

The M65 Ultra Wireless is exactly what I'm looking for in a wireless gaming mouse.

Without lighting, Corsair claims up to 120 hours of battery life when using Bluetooth (90 hours when using Slipstream). After 15 minutes, however, the mouse automatically sleeps, so you can use the M65 for weeks without charging. Compared to my Razer Viper Ultimate, I haven't felt the loading error nearly as often. And when I did, the USB-C port for charging meant I was rarely without a replacement cable.

The M65 Ultra Wireless is exactly what I'm looking for in a wireless gaming mouse. The quick switching between 2.4 GHz wireless and Bluetooth makes the mouse versatile for different setups and the battery lasts long enough to never feel like a problem. USB-C is a big win too, unlike mice like the Razer Viper Ultimate, which stuck with a micro-USB port.

software

Corsair's iCue software is one reason to choose the M65 Ultra Wireless. As with Logitech's G Hub and Razer's Chroma, iCue lets you customize RGB lighting and change key assignments, including assigning absurd macro functions to each of the keys. Once you have everything set up, you can save your DPI, lighting and macro profile on the mouse for use without iCue.

There's not much in terms of lighting as the M65 Ultra Wireless has a single zone for the logo on the back. However, iCue gives you access to custom lighting effects like rain or a temperature sensor. I have a penchant for static lighting in my rig, which iCue divides into a separate, simplified section.

The most fascinating part of iCue with the M65 Ultra Wireless is the gyroscope. The six-axis gyroscope enables the configuration of the lift detection, but also opens up the possibility of gestures. The M65 Ultra Wireless includes forward, backward, left and right tilt gestures that you can assign to any key or macro like a normal key.

And to my surprise, it works. I can't imagine ever using the tilt feature – immediately after setting it up, I accidentally frenzied the mouse after turning it upside down – but it works. There are also some uses for it such as For example, using Alt + Tab to scroll through windows or assign a key like PrintScreen that you might otherwise have to look for.

Corsair's iCue is an integral part of the M65 Ultra Wireless. It goes well beyond buttons and lighting, and gives you access to unique features like gestures and important settings, such as: B. when the mouse goes to sleep.

Our opinion

The Corsair M65 Ultra Wireless targets two other mice directly – the Logitech G Pro and the Razer Viper Ultimate. The Viper Ultimate is about $ 20 more expensive, while the M65 and G Pro are both $ 130. In terms of performance, there isn't much of a difference between these three mice, so it comes down to features and preferences.

The Corsair mouse has a number of advantages in this regard. The optical switches are faster, it contains a massive battery and comes with USB-C for charging. I also love the design and feel of the M65, though a lot of it depends on your hand size and the way you hold your mouse.

I would have liked a slightly cheaper price – around $ 110 like the Saber Pro Wireless – but the M65 still feels a step ahead of the competition.

Are there alternatives?

Yes, several. For high-end wireless FPS mice, the Razer Viper Ultimate, Logitech G Pro X Superlight, and Corsair Saber Pro Wireless are all options.

You can save a lot with a wire too. Corsair's wired M65 is $ 60 cheaper, and there are options like the SteelSeries Rival 3 for around $ 30.

How long it will take?

Omron optical switches do not have the same 50 million click lifespan as mechanical switches. Most optical switches, however, last longer than mechanical ones. The M65 Ultra Wireless should last 15 years or more, long gone when you're likely to want to switch to something new.

Should you buy it?

Yes sir. The M65 Ultra Wireless is an excellent wireless gaming mouse. It has the same premium features as similar mice like the Razer Viper Ultimate and the Logitech G Pro X Superlight. However, you can save a lot with inexpensive wireless options like the Logitech G305 or the wired version.
