The Bloody R72 Ultra Duo Wireless Gaming Mouse combines a lightweight 70g design with Bloody’s Alpha 20K sensor, adjustable sensitivity up to 20,000 CPI, a 1000Hz polling rate and 1ms 2.4GHz wireless transmission. Its Duo setup includes both a compact nano receiver and an L++ desktop receiver dock that also provides magnetic charging and battery-level indication. A 300mAh rechargeable battery delivers up to 75 hours of rated playtime, while wired USB-C operation gives you another way to keep playing while charging.

 

Lightweight Wireless Performance for Gaming

The Bloody R72 Ultra Duo is built for players who want the freedom of wireless gaming without moving to a hevy mouse. At approximately 70g without the cable, its 125 × 63 × 40mm body keeps the overall setup relatively light while still providing a conventional full-shell design. Smooth-glide mouse feet are used underneath to reduce resistance during fast movements and smaller aim corrections.

Alpha 20K Sensor with Adjustable CPI

At the centre of the mouse is Bloody's Alpha 20K Engineered Engine. Its six default CPI stages are 400, 800, 1000, 1200, 1600 and 2000 CPI, allowing quick adjustments directly from the mouse.

For users who want more specific sensitivity settings, Bloody's software extends adjustment from 50 up to 20,000 CPI. The sensor is rated for up to 350 IPS tracking speed and 40G acceleration, giving it the tracking specifications required for fast mouse movements in FPS, battle royale and other competitive games.

Dedicated CPI + and - controls also make it possible to change the preset sensitivity without opening the software during a game.

1000Hz Polling and 1ms Wireless Transmission

The R72 Ultra Duo supports an adjustable report rate of up to 1000Hz. Bloody specifies 1ms wireless transmission when operating at 1000Hz, while its WaveLink wireless system incorporates channel-locking and anti-interference measures intended to maintain a stable 2.4GHz connection.

Dual 2.4GHz Receiver System

The “Duo” part of the R72 Ultra Duo is particularly useful for users who switch between a desk setup and portable use.

Two 2.4GHz receiver options are provided:

• L++ Multi-Function Receiver Dock for a desktop gaming setup
• Nano USB Receiver for laptops and portable use

A switch on the underside of the mouse selects which receiver is active. The centre position switches the mouse off.

The desktop L++ dock does more than receive the wireless signal. It provides snap-on magnetic charging, instant pairing and a four-stage battery indicator, so the mouse can be placed on the dock when it needs chargng instead of connecting the charging cable directly every time

Wired USB-C Gaming When Required

The R72 Ultra Duo can also operate in wired USB mode. Connecting the USB Type-C cable automatically changes the mouse from wireless to wired operation, and the internal battery charges at the same time.

Bloody supplies two 180cm USB Type-C cables with the Duo package. 

This gives users the option to keep one cable connected to the receiver dock while keeping another available for direct wired operation or charging.

300mAh Rechargeable Battery

Inside the mouse is a 300mAh lithium battery. Bloody rates charging time at 1.5 hours or less and playtime at up to 75 hours, depending on operating conditions and settings.

Charging can be performed through the USB Type-C port on the mouse or by placing the mouse on the magnetic L++ charging dock. The mouse's function indicator also communicates charging status, including a low-battery warning when the remaining level falls below 15%.

Seven Programmable Buttons and AFC Clicking

The R72 Ultra Duo has seven programmable buttons. Bloody's AFC (Anypoint Flexible Click) technology is designed to maintain smooth and consistent clicking across different finger positions on the main buttons, while its RapidSnap Rebound system is intended to maintain responsive button rebound.

Bloody rates the left and right main micro-switches for more than 30 million clicks, while the scroll wheel is rated for more than 800,000 scrolls.

Bloody Wireless M-Esports Software

The mouse can be configured through Bloody's wireless mouse software. Users can adjust functions such as:

• Button assignments
• Sensitivity
• Button combinations
• Keyboard and mouse combinations
• Macro commands
• Saved mouse configurations

Bloody also specifies 512KB of onboard memory for the R72-series models, allowing programmed settings to be stored in the mouse.

The current official R72 Ultra Duo software page lists Windows 10 and Windows 11 for the Bloody Wireless M-Esports Editor.

Compatibility & Ideal Use Guidance

PC Gaming

The R72 Ultra Duo is best suited to a desktop or laptop gaming setup where its 1000Hz report rate, 20,000 CPI sensor capability, seven programmable buttons and 2.4GHz wireless connection can be fully used.

For a permanent desktop setup, the L++ receiver dock is the more convenient wireless connection because it keeps the receiver close to the mouse and also functions as the magnetic charging dock.

FPS and Competitive Games

The combination of a 70g body, 350 IPS tracking, 40G acceleration and 1000Hz polling makes the R72 Ultra Duo particularly relevant for games involving rapid aiming and frequent mouse movement, including FPS, battle royale and other action-oriented titles.

General and Productivity Use

Sensitivity adjustment and programmable buttons can also be useful for browsing, editing and everyday PC work, particularly for users who prefer switching between lower and higher cursor sensitivity depending on the task.

USB-C Devices

Bloody supplies USB/Type-C adapters and specifically references devices such as MacBook and Chromebook when describing Type-C connectivity. However, Bloody's current configuration software for this mouse is officially listed for Windows 10/11. Therefore, customers who require macro programming or advanced software configuration should use a compatible Windows PC.

Important Connection Note

The R72 Ultra Duo uses 2.4GHz wireless or wired USB connectivity. Bluetooth is not one of the connection modes listed by Bloody, so buyers specifically looking for Bluetooth pairing should keep this distinction in mind.

Frequently Asked Questions

3. Does the Bloody R72 Ultra Duo have Bluetooth?
