Transparent Crystal Shell Design

The ASUS m21 white HXMJ is a right-handed gaming mouse wrapped in a fully transparent PC shell with high-purity PP crystals. It weighs 110g and measures 128 by 77 by 40 millimetres. The optical sensor offers five adjustable resolution steps from 1200 to 3600 and a maximum speed of 60 inches per second. The package includes a USB receiver and a 1.6 metre charging cable.

Tri-Mode Connectivity Upgrade

This mouse replaces single-mode wired or basic wireless pointers by adding Bluetooth 5.0 and 2.4 GHz wireless alongside the wired USB connection. The jump is worth it when you switch between a desktop, a laptop and a tablet without re-pairing. Polling rate defaults to 500 Hz and can reach 1000 Hz for competitive play. The 20 million click switch life supports long-term heavy use.

Plug-and-Play With a Firm Cable Seat

Installation is straightforward: plug the receiver or cable and the mouse is ready, no driver required. The mode switches automatically to wired when the cable is connected. A common issue is the tight USB-C port; you must push until you hear a click to seat the cable properly. The bottom button toggles the 13 RGB modes and powers the lighting on or off.

Questions about this item

Does the 128×77×40 mm shell and 110 g weight need a specific hand size or grip style?

The adjustable grip design suits right-handed users across a range of hand sizes; the lightweight crystal shell keeps fatigue low during long sessions.

How do I pair the mouse in Bluetooth 5.0 mode, and what is the step users often miss?

Hold the bottom mode button until the indicator flashes, then select the mouse in your OS Bluetooth menu; the common miss is forgetting to unplug the 1.6 m cable first.

When will the switches rated for 20 million clicks or the PTFE feet need replacement?

Switches are rated for 20 million clicks; PTFE feet wear depends on pad roughness and daily hours, so inspect them periodically and replace when glide feels uneven.
