Pulsar has launched the X2F CrazyLight, a wireless gaming mouse built for fingertip grip and weighing a claimed 29 grams, plus or minus 2 grams. It pairs its stripped-down shape with an XS-2 optical sensor, polling rates up to 8,000Hz, and a reported $149.95 price, placing it in the premium lightweight category.
Key takeaways
The X2F CrazyLight prioritizes low weight and fingertip control, rather than offering a conventional full-size mouse shape.
- Claimed weight: 29 ± 2 grams
- XS-2 sensor: up to 42,000 CPI, 800 IPS, and 70G acceleration
- Wireless polling rate: up to 8,000Hz with the Link 2 dongle
- Price: $149.95
A shape built around fingertip control
The X2F CrazyLight measures 87.5 × 61.1 × 31.6 mm and uses an ABS-and-nylon composite shell. Its compact, symmetrical design removes much of the rear body found on conventional mice, focusing the shape on the main buttons. Pulsar is targeting players who move the mouse with their fingertips; the reduced form factor may not suit every grip style or hand size.
The mouse includes both dot skates and full-cover feet, giving users options for how the base contacts the pad. It has no lighting, and its listed connectivity supports both wireless and wired use. A 210mAh battery powers wireless operation.
Sensor and 8K polling features
Pulsar’s XS-2 optical sensor is rated for up to 42,000 CPI, 800 IPS tracking, and 70G acceleration. It also supports adjustable lift-off distance, with adjustment reported in 0.1mm increments. A 20K high-frame-rate mode is available, though using a higher performance mode can affect battery life.
The mouse supports polling rates up to 8,000Hz, sending reports to the PC more frequently than standard 1,000Hz polling. The Link 2 dongle provides onboard controls for settings including DPI and polling rate, with further customization available through Pulsar’s Bibimbap browser interface or its downloadable driver.
Switches, controls, and price
Pulsar rates the optical main switches for 100 million clicks. The scroll wheel uses a TTC Gold encoder, while the five-button design keeps controls focused on core mouse functions. The Link 2 receiver has two buttons and can store up to four profiles, allowing users to switch profiles or adjust selected settings without opening the software after initial setup.
Pulsar lists the X2F CrazyLight at $149.95. The package includes the mouse, Link 2 dongle, USB-C cable, and two types of skate sets. Its price and specialized shape make it a focused option for competitive players who value minimal weight and high polling rates over a more broadly accommodating mouse design.
