Design
The Pulsar Susanto-X wireless gaming mouse comes in a compact, symmetrical design with dimensions of 118.7 x 62.3 x 38.6 mm. It is well-suited for medium-sized hands and works best with claw or fingertip grip styles. At only 50 grams, it is lightweight and easy to move while still feeling solid in use. The matte black shell has a smooth finish that resists fingerprints and stays comfortable during long sessions. Its shape supports both right- and left-handed users, offering a natural feel that adapts easily to different grip preferences. Claw and relaxed claw grips in particular benefit from the balance between control and comfort.
In terms of design, the mouse features pink accents on the scroll wheel, side buttons, and base rim, along with a “Susanto Brothers” logo on the side to mark the collaboration. The build quality is firm with no flex or creaking in the shell, and the buttons provide sharp, consistent clicks. These details give the Susanto-X a dependable character, pairing a clean look with practical features that make it suitable for extended gaming use.
The left and right buttons feature a gentle inward curve that helps the fingers rest naturally, improving grip and control. Both are fitted with Pulsar’s 100M-click optical switches, which provide light, responsive clicks with consistent tactile feedback. During use, the buttons showed no pre-travel or side movement, and inputs registered quickly, even with repeated presses.

Features and Performance
The Susanto-X is built around the XS-1 sensor, supporting up to 32,000 DPI, 750 IPS tracking, and 50g acceleration. With an 8000Hz polling rate and a 1ms response time, inputs register quickly and remain consistent, which is important in competitive play. A 32-bit ARM processor manages data flow to maintain accuracy during fast movement, reducing the chance of tracking loss under heavy load.
The sensor integrates PixArt’s Motion Sync, a feature that synchronizes signal output with the PC’s data extraction cycle. This minimizes delay and improves tracking precision, measured at under 1ms. Motion Sync can be toggled through the Pulsar Fusion Software, giving players control over how the sensor behaves.
Three LOD options—2mm, 1mm, and 0.7mm—are available for players who prefer different sensor cut-off points. This helps maintain cursor accuracy when repositioning the mouse, particularly for low-DPI users.
Turbo Mode fixes the sensor at 20,000 FPS, reducing initial micro-delays when movement begins. This ensures smooth pixel tracking from the start, which is valuable for precise aiming. The feature is tuned for low-DPI gameplay, maintaining stability across different DPI and polling rate settings.
DPI can be adjusted in fine steps, polling rates can be configured, and button remapping with macros is supported through the software. This level of control makes the Susanto-X adaptable across different game types, from fast shooters to slower-paced strategy titles.
The mouse uses Pulsar optical switches rated for 100 million actuations, providing consistent actuation and long-term reliability. The Pulsar Blue encoder adds accurate scroll steps, which improve weapon switching and precision adjustments.
In testing, the mouse tracks smoothly across both rapid flicks and small aim corrections. The high polling rate reduces input delay, resulting in responsive control even in demanding situations. Combined with durable switches and broad customization options, the Susanto-X maintains steady performance for competitive gaming.
Connectivity
The Susanto-X Mouse lets you switch between wired and 2.4GHz wireless modes with a simple toggle on the bottom. The 2.4G wireless connection uses the included 8K Wireless Dongle and provides a stable, low-latency link, making it suitable for gaming. Bluetooth isn’t supported, but the wireless performance remains consistent, whether for gaming or everyday tasks.
In wired mode, the mouse connects through a detachable USB-C cable that also charges the internal battery, so you can keep using it while it charges. Switching between wired and wireless is quick and reliable, and the mouse performs consistently across both modes. Its design and connectivity make it a practical choice for gaming setups as well as general use.
Pulsar’s Software
Pulsar’s software for the Susanto Wireless mouse is designed with a clean layout that makes setup and adjustments simple. The starting screen highlights the mouse with a clear label, allowing users to quickly access settings without distractions. Key options are divided into four sections—Main, Button Assignment, Performance, and Macro—covering everything from firmware updates and pairing to general system preferences. The Main tab also includes a battery level indicator, useful for keeping track of power status, while additional options such as startup behavior and quick access to Windows Mouse Properties provide practical control. Firmware reminders are also present, ensuring the device runs on the latest version for stable performance.
The Button Assignment tab provides full remapping of all inputs with a helpful visual layout of the mouse, making customization easy to follow. Features like Turbo Mode, Motion Sync, and adjustable debounce timing give players room to fine-tune their settings, while the Auto Sleep function helps extend battery life. The Performance tab expands control with six DPI stages reaching up to 32000 DPI, polling rates that scale up to 8,000 Hz, and adjustable lift-off distance. Sensitivity and double-click speed sliders further enhance precision, while the absence of lighting effects keeps the focus on performance features. Overall, the software delivers a functional set of tools that support both everyday use and competitive play.
Battery and Charging
The Susanto-X comes with a 300mAh rechargeable battery, almost twice the size of what many other lightweight gaming mice offer. In testing, it handled long gaming sessions and regular desktop use easily, lasting around 5 to 7 days on a single charge, even with the 8K polling rate enabled. For a mouse this small and light, that kind of battery life is convenient, letting users focus on gaming without worrying about frequent recharges.
Charging is done through a USB-C port and takes about two hours from empty to full. The battery performs well compared to larger wireless models, offering a good mix of power and efficiency. It keeps the mouse ready for extended gaming or work sessions, so running out of charge in the middle of use isn’t a concern.
Use Experience – Daily Work and Gaming
Using the Pulsar Susanto-X daily over a two-week period showed how well it balances gaming performance with regular work. The mouse feels very light in the hand, making it easy to move across the desk with minimal effort. The symmetrical shape and low profile supported longer sessions without hand strain, which was noticeable during hours of browsing, typing, and multitasking between applications. The optical switches kept clicks consistent and sharp, whether it was for gaming inputs or routine productivity tasks.
During desktop work, the PTFE feet provided a smooth glide on both cloth and hybrid pads. Even on a plain desk surface, the sensor tracked reliably without stutter or drift. Battery performance also held up well: with the polling rate set to 8,000 Hz, the mouse lasted nearly a week before charging was necessary. Dropping to 1,000 Hz stretched battery life even further, which is useful when the mouse is used more for work than gaming.
In competitive shooters such as Valorant and Counter-Strike 2, the Susanto-X delivered the precision expected from a product shaped by professional input. The XS-1 sensor maintained accurate tracking through fast flicks and smaller aim corrections, and the higher polling rate reduced input delay to a point where actions felt immediate. The grip angle and shell curvature gave reliable control during extended play, with no comfort issues after multiple hours.
Outside of shooters, the mouse also performed well in strategy and MMO titles. Switching DPI profiles through Pulsar’s software allowed quick adjustments for different game types, while the side buttons were positioned within easy reach for assigning skills or commands. Throughout two weeks of use, the buttons and scroll wheel retained a firm, consistent feel, with no looseness or change in performance.
After extended daily use, the Susanto-X proved to be dependable across both gaming and general work. Its lightweight, stable tracking, and efficient battery performance made it practical for day-to-day tasks, while its professional-level design translated effectively into competitive play. The mouse held up as a reliable option for users who divide their time between gaming and regular desktop activity.
