M8 Wireless

Overview

The Xtrfy M8 Wireless is a 58g wireless gaming mouse from Swedish peripheral maker Xtrfy, released in 2023. It was built from the ground up as a claw grip specialist — a mouse that does not try to be everything to everyone but instead commits fully to serving one grip style exceptionally well. The M8’s shape is immediately recognizable and unlike anything else on the market: a low front that rises to a supportive rear hump, creating a natural cradle for claw grip hand positioning. Powered by a PixArt PAW3395 sensor and Kailh GM 8.0 switches, it pairs its unique shape with modern, competitive internals at $89.99.

Design & Build Quality

The M8 Wireless makes an immediate visual impression. Its shell has a distinctive angular profile with flat sides that taper toward the front, creating a shape that looks as purposeful as it feels. Dimensions are 125.0 x 65.0 x 40.0mm — compact enough for small-to-medium hands but with enough width to provide a stable grip surface.

Build quality is excellent for the weight class. At 58g, many ultralight mice sacrifice structural integrity, but the M8 Wireless has no shell flex when squeezed or twisted. There is no creak, no rattle, and the primary buttons are solid with minimal wobble. Xtrfy achieved this rigidity without resorting to honeycomb cutouts — the shell is fully closed.

The coating is Xtrfy’s EZcord matte surface, which provides good grip in both dry and slightly sweaty conditions. It does not pick up oil marks as aggressively as some glossy alternatives, though it is not quite as grippy as VAXEE’s coating.

No RGB lighting is present, consistent with the competitive focus. The mouse offers six buttons: two main clicks, scroll wheel click, two side buttons, and a DPI button. The clean design uses a single color scheme (available in black or white) without branding excess.

The USB-C port sits at the front of the mouse for charging, and the included 2.4GHz dongle stores in a compartment on the underside.

Shape & Grip Compatibility

The M8 Wireless’s shape is its defining feature and the reason to consider this mouse over more conventional alternatives. The front of the mouse sits noticeably lower than the rear, with the hump positioned in the back third of the shell. This creates a natural hand position where your fingertips rest on the buttons while the rear hump pushes up into the back of your palm.

Claw Grip: This is the primary design target, and the M8 delivers. For hands measuring 17.0 to 19.5cm in length and 8.5 to 10.0cm in width, the shape creates an ideal claw grip cradle. The low front (approximately 30mm at the button surface) means your fingers can arch naturally over the main buttons without hitting a tall nose. The rear hump rises to 40.0mm, pushing into the back of your palm and locking the mouse in position. The flat sides provide secure contact points for your thumb and ring/pinky fingers.

What sets the M8 apart from other claw mice is the transition from the low front to the high rear. Rather than a gradual slope, the M8 has a more defined rise point that creates a distinct shelf your palm rests against. This gives you a strong sense of where the mouse is in your hand at all times — critical for the fast micro-adjustments claw grip relies on.

For hands measuring 18.0 to 19.0cm, the claw grip fit is nearly perfect. Your wrist stays in a neutral position, your fingers have full freedom of movement on the buttons, and the rear hump provides just enough support without forcing your palm into a flat position.

Fingertip Grip: Very good for small-to-medium hands (16.5 to 18.5cm). The 58g weight means your fingertips can control the mouse without fatigue, and the compact dimensions allow easy repositioning. The flat sides help prevent the mouse from rotating during quick flicks. The low front is particularly beneficial for fingertip grip because it keeps your fingers at a comfortable angle.

Palm Grip: Workable for hands measuring 17.0 to 19.0cm, but not the intended use case. The low front means your fingers extend further forward than they would on a mouse with a taller nose, which can create an unnatural hand angle for palm grip. The rear hump provides good support, but the overall shape encourages claw positioning rather than full palm contact.

Recommended hand size: 17.0 to 19.5cm in length and 8.5 to 10.0cm in width.

Sensor Performance

The PixArt PAW3395 is one of the best gaming mouse sensors available and is flawless in the M8 Wireless. DPI range spans 400 to 19,000, adjustable through Xtrfy’s software. At competitive DPI settings (400 to 1600), tracking is impeccable with zero smoothing, zero acceleration, and consistent performance across all pad surfaces.

Maximum tracking speed is rated at 400 IPS with 40G acceleration tolerance. Lift-off distance is approximately 1.0mm and adjustable. Motion latency measures approximately 5.0ms, and click latency is around 2.0ms — competitive figures for a 2.4GHz wireless mouse.

The PAW3395 is power-efficient enough to deliver strong battery performance without compromising tracking accuracy. For competitive FPS play, this sensor is indistinguishable from any other top-tier option.

Switches & Buttons

The Kailh GM 8.0 switches are a highlight. Rated for 80 million clicks, they provide a crisp, satisfying click with a light actuation force of approximately 52gf. The tactile break is clean and defined, and the return snap is quick. These switches are widely regarded in the enthusiast community as among the best stock mechanical switches available in a gaming mouse — they rival or exceed the click feel of much more expensive mice.

The scroll wheel uses mechanical stepped encoding with medium-weight, well-defined notches. Each step provides clear tactile feedback for weapon switching and menu navigation. The encoder is reliable with no scroll inconsistency.

Side buttons are accessible and have a satisfying click with minimal pre-travel. The DPI button is positioned on the underside to prevent accidental presses during gameplay.

Connectivity & Battery

The M8 Wireless connects via 2.4GHz wireless using an included USB-A dongle. There is no Bluetooth option. A USB-C port allows charging and wired play as a backup connection.

Battery life is rated at 90 hours, with real-world usage typically landing between 65 and 75 hours at 1000Hz polling. For daily 4 to 6 hour gaming sessions, you can expect approximately two weeks between charges. USB-C charging takes roughly 2 hours from empty.

Supported polling rates are 125, 250, 500, and 1000Hz. The 1000Hz maximum is standard for this price range, though it does mean you miss out on the 4000Hz+ options available on premium mice.

Feet & Glide

Four large PTFE feet with approximately 0.8mm thickness provide an excellent glide surface. The stock feet are notably good — smooth and consistent on cloth pads with controlled speed on hard pads. The generous foot surface area provides stable tracking and even weight distribution. Out-of-box glide quality is above average, and many users find no need for aftermarket replacements.

Aftermarket feet from Corepad and Tiger Arc are available for the M8 footprint if you want to customize the glide characteristics.

Software

Xtrfy’s software takes a minimal approach. You can adjust DPI, polling rate, lift-off distance, and button assignments. One onboard memory profile stores settings directly on the mouse. There are no macro features and no complex customization layers.

This minimalism is intentional — Xtrfy targets competitive players who want to set their configuration once and play without software running. The tradeoff is limited customization for users who want macro programming or per-game profiles.

Pro Player Usage

The M8 Wireless does not appear on any tracked professional players’ setups in our database. Xtrfy has a smaller market presence than Razer, Logitech, or SteelSeries, and the M8’s unique shape means it appeals to a self-selected audience rather than benefiting from broad pro sponsorship deals.

However, the mouse has developed a strong following in the enthusiast community, particularly among claw grip players who have tried numerous shapes. The M8 frequently appears in recommendation threads on r/MouseReview for claw grip users with small-to-medium hands.

The lack of pro adoption should not be interpreted as a performance limitation. The PAW3395 sensor and Kailh GM 8.0 switches are competitive with any mouse used in professional play. The barrier is brand visibility and the niche shape, not hardware capability.
