Endgame Gear XM2w vs Glorious Model O Wireless

Introduction

The Endgame Gear XM2w and the Glorious Model O Wireless both sit at approximately $80 and both offer symmetrical wireless gaming mouse experiences. That is where the similarities end. The XM2w is a 60-gram claw grip specialist built with 2026-era components — PAW3395 sensor, Kailh GM 8.0 switches, dual-mode connectivity. The Model O Wireless is a 69-gram FK-clone with honeycomb shell, the older BAMF sensor, and 2.5ms click latency that betrays its age.

I will be direct: the Endgame Gear XM2w is the significantly better mouse. The Model O Wireless was groundbreaking when it launched, but the market has evolved, and it has not kept pace. The XM2w represents everything that has improved in the lightweight mouse category — better sensor, better switches, lower latency, lighter weight without holes in the shell, and dual-mode wireless. At the same price, this should not be a difficult decision.

But context matters. The Model O Wireless still has its niche. If you specifically need an FK-clone shape — flat, long, low-profile — and you want it wireless, options are limited. Let me explain when each mouse makes sense.

Quick Verdict Table

Shape & Ergonomics

The XM2w is purpose-built for claw grip. The hump is positioned toward the rear of the mouse, which pushes against the base of your palm and creates a natural pocket for your arched fingers. The width is moderate, the sides are flat for secure grip, and the overall dimensions support aggressive claw without forcing you into an uncomfortable position. For hands measuring 17.5-20 cm in length and 9-10.5 cm in width, this is one of the best claw shapes on the market.

The Model O Wireless is an FK1-clone: long, flat, and low-profile. The hump is minimal and centered, which makes it feel like a surfboard under your hand. This shape was popularized by Zowie and has a dedicated following among players who prefer a flat symmetrical mouse for fingertip or relaxed claw grip. For hands measuring 18-21 cm, the FK-clone shape works for fingertip grip. For claw grip with hands under 19 cm, it can feel too long and too flat.

Palm grip: Neither mouse is designed for palm grip. The XM2w’s rear hump provides partial palm support for a palm-claw hybrid with medium hands (18-19.5 cm). The Model O Wireless is too flat for palm grip under any circumstances. If you palm grip, neither of these mice is for you.

Claw grip: The XM2w is the clear winner. Its rear hump, moderate width, and carefully tuned dimensions make it one of the best claw mice available at any price. The Model O Wireless can work for relaxed claw with larger hands (19.5+ cm), but it lacks the intentional claw-optimized geometry of the XM2w. The difference is immediately apparent when you switch between them.

Fingertip grip: The Model O Wireless is better for pure fingertip. Its flat, elongated shape provides a stable platform for fingertip control with larger hands (19-21 cm). The XM2w’s rear hump can feel intrusive during fingertip grip. If you are a committed fingertip player, the Model O shape is more suitable, though at 69 grams it is heavier than ideal for the grip style.

Sensor & Tracking

This is not a close comparison. The PAW3395 in the XM2w is the current gold standard for gaming mouse sensors. It tracks perfectly, has negligible CPI deviation, handles any surface, and supports DPI up to 26,000 with zero smoothing at competitive settings. The BAMF sensor in the Model O Wireless is a custom sensor from Glorious that, while adequate, does not match the PAW3395’s precision, surface compatibility, or motion sync capabilities.

In practical terms, both sensors will track competently during normal gameplay. You are unlikely to miss shots because of the BAMF sensor. But the PAW3395 provides noticeably better tracking during aggressive swipes on low DPI, handles lift-off distance more precisely, and works consistently on a wider variety of pad surfaces. If you switch between multiple mousepads or play on low DPI (400-800), the PAW3395’s advantages become tangible.

Build Quality & Switches

The XM2w uses a solid plastic shell with no holes. It feels sturdy, uniform, and well-constructed. Endgame Gear has a strong reputation for build quality, and the XM2w lives up to it. The buttons have minimal pre-travel, the scroll wheel has defined steps, and the side buttons are crisp and well-positioned.

The Model O Wireless uses a honeycomb shell. In 2020, this was an innovative approach to weight reduction. In 2026, it is an outdated compromise. Honeycomb shells collect dust and debris inside the mouse, feel less rigid under pressure, and create an uneven texture under your fingers. The Model O Wireless weighs 69 grams despite the holes — the XM2w weighs 60 grams with a solid shell. Engineering has simply moved past honeycomb designs.

The switch difference is significant. The XM2w uses Kailh GM 8.0 switches — 80 million click lifetime, crisp actuation, excellent tactile feedback. The Model O Wireless uses Omron-based switches that, while functional, lack the sharpness and longevity of the Kailh GM 8.0. Click latency tells the story: the XM2w achieves approximately 1.5ms while the Model O Wireless sits at 2.5ms. That is a 40% latency advantage for the XM2w.

Battery & Wireless

The XM2w offers approximately 70 hours of battery life on 2.4GHz and adds Bluetooth connectivity for productivity use. The Model O Wireless provides roughly 60 hours on 2.4GHz with no Bluetooth option. The XM2w wins on both endurance and versatility.

The dual-mode connectivity on the XM2w is genuinely useful. Switch to Bluetooth for browsing or work, switch back to 2.4GHz for gaming. One mouse, two use cases, no compromise. The Model O Wireless is locked to its 2.4GHz dongle for everything.

Both mice charge via USB-C. Connection stability on 2.4GHz is good for both, with no noticeable lag or dropout during competitive play. The XM2w’s wireless implementation is simply newer and more feature-rich.

Software

Endgame Gear’s software is lightweight and functional. DPI stages, polling rate, lift-off distance, debounce time, angle snapping, and button remapping are all configurable. Settings save to onboard memory. The software installs quickly and does not run in the background.

Glorious Core is more full-featured but heavier. It supports macro programming, RGB control (the Model O Wireless has RGB lighting), and profile management. If you value RGB customization, the Model O Wireless offers more here. If you just want to configure your mouse and move on, the XM2w’s software is leaner and less intrusive.

The Model O Wireless does have RGB lighting through its honeycomb shell, which some users appreciate aesthetically. The XM2w has no RGB — it is designed purely for function. This is a matter of personal preference, but RGB adds weight, battery drain, and complexity with no competitive advantage.

Price & Value

Both mice sit at approximately $80 (XM2w at ¥11,000, Model O Wireless at ¥10,800). At effectively the same price point, this becomes a pure feature comparison — and the XM2w wins in nearly every measurable category.

Better sensor (PAW3395 vs BAMF). Better switches (Kailh GM 8.0 vs Omron). Lower weight (60g vs 69g). Lower click latency (1.5ms vs 2.5ms). Longer battery (70h vs 60h). Bluetooth connectivity. Solid shell. The XM2w offers more technology at the same price. The Model O Wireless’s only advantages are its FK-clone shape (if you specifically need it) and RGB lighting (if you care about aesthetics).

The value proposition is not close. The XM2w is one of the best values in the $80 price bracket. The Model O Wireless is an aging product being sold at the same price as its far more capable competitor.

Who Should Buy Which

Buy the Endgame Gear XM2w if:

• You use claw grip with hands measuring 17.5-20 cm in length
• You want the best sensor, switches, and latency available at $80
• You need both 2.4GHz gaming performance and Bluetooth productivity connectivity
• You prefer a solid shell without honeycomb holes
• You want a purpose-built competitive mouse with no unnecessary features

Buy the Glorious Model O Wireless if:

• You specifically need an FK-clone shape and no alternative will do
• You use fingertip grip with hands measuring 19-21 cm
• You want RGB lighting through a honeycomb shell for aesthetic reasons
• You already own one, are happy with it, and see no reason to switch
• You found it heavily discounted below its $80 retail price

Final Verdict

The Endgame Gear XM2w is the better mouse by a wide margin. It is lighter, faster, more versatile, and built with superior components, all at the same price. The claw grip ergonomics are exceptional, the PAW3395 sensor is flawless, the Kailh GM 8.0 switches are crisp, and the dual-mode wireless adds genuine daily utility. There is no performance category where the Model O Wireless wins.

The Model O Wireless deserves respect for what it accomplished — it helped popularize lightweight wireless gaming mice and made ultralight accessible at a reasonable price. But in 2026, it is outclassed. The honeycomb shell is outdated engineering. The BAMF sensor is a generation behind. The 2.5ms click latency is no longer competitive at this price point.

If you are choosing between these two mice today, buy the XM2w. If you already own a Model O Wireless and it works for you, keep it — but know that the XM2w represents a meaningful upgrade whenever you are ready. The claw grip specialists at Endgame Gear built something genuinely excellent here.
