The Pulsar X2N CrazyLight is a wireless gaming mouse that continues Pulsar's X2 series. It has a symmetrical shape with a higher hump and wider rear end than other mice in the X2 lineup. It uses the same optical left-and right-click switches, a Pulsar-branded blue scroll wheel encoder, and an XS-1 sensor (a Pulsar-exclusive sensor based on PixArt's PAW 3950) as the Pulsar X2 CrazyLight. It has a maximum polling rate of 8000Hz out of the box and comes with large-sized PTFE feet installed on the mouse as well as a sheet of alternate dot skates, which are generally preferred for harder mouse pads.
Our Verdict
While primarily designed for gaming, the Pulsar X2N CrazyLight is decent for work use. It boasts excellent build quality and connects wirelessly via its 2.4GHz receiver. You can program all its buttons using either the downloadable or web-based configuration software. However, it lacks Bluetooth connectivity and useful productivity features like a free scrolling mode or L/R scroll wheel inputs.
Excellent build quality.
Comfortable symmetrical shape.
Open bottom plate leaves the inside open to dust and debris.
Small battery helps reduce weight at the cost of battery life.
Lacks Bluetooth and multi-device pairing.
The Pulsar X2N CrazyLight is an outstanding mouse for FPS gaming. Its extremely lightweight design allows for quick and accurate movement. Its symmetrical shape is well-suited for claw and relaxed claw grips, making it comfortable if you have medium or large-sized hands. Performance-wise, it supports a wireless polling rate of 8000Hz and offers exceptionally low click and sensor latency, making it ideal for competitive play. However, while its relatively small battery size lowers its weight, it requires frequent recharging, especially at higher polling rates. Additionally, its open baseplate design helps save weight but leaves the interior of the mouse vulnerable to dust and debris collection.

The Pulsar X2N CrazyLight is a great choice for MMO and MOBA gaming, although it lacks the number of side buttons typically found in MMO mice. However, you can program buttons and create macros using the downloadable software. The mouse boasts excellent build quality and exceptional overall performance. A minor downside is its open baseplate design, which helps make it lightweight but also leaves the interior exposed to dust and debris.

Differences Between Sizes And Variants
The Pulsar X2N CrazyLight is available in mini or medium sizes, and in Jet Black, Uyuni White, and Ocean colorways. We bought and tested the medium-sized variant in Ocean. You can see a photo of our unit's label here.
This mouse is part of Pulsar's X2 series of lightweight wireless gaming mice. We expect many of our test results to broadly apply to other models in the series, though we expect differences between models with different sensors, sizes, shapes, or due to features like additional buttons. We've chosen not to include a list here since it would quickly become outdated considering how many new products and variants Pulsar releases.
Popular Mouse Comparisons
The Pulsar X2N CrazyLight is yet another addition to Pulsar's expanding X2 lineup of lightweight gaming mice. This version boasts a new shape designed for claw and relaxed-claw grip users. The shape is rather bulbous, with a wide rear end and a high-profile hump that flattens out more gradually than on other mice in the lineup, like the Pulsar X2 CrazyLight or the Pulsar X2H v3.
This mouse occupies the upper mid-range price category, and is a compelling option if you're looking for a top-performing, extremely lightweight mouse with a subtly unique shape that's well-suited for claw grippers with medium to large hands. Options like the Razer Viper V4 Pro and the Logitech G PRO X SUPERLIGHT 2 deliver comparable performance with decidedly more 'safe' shapes that are well-suited for a wider variety of hand sizes.

The Pulsar X2N CrazyLight and Razer Viper V4 Pro are both outstanding wireless FPS gaming mice. The Razer has a more conventional symmetrical shape that's suitable for a variety of hand sizes and grip styles, while the Pulsar's shape is optimized more for claw and relaxed claw grips for medium to large hand sizes. The Pulsar is a few grams lighter, but has an open bottom plate and a smaller battery to help achieve the weight savings, meaning the internal components are more susceptible to collecting dust and debris, and you won't be able to use the mouse for as long without recharging.
The Pulsar X2N CrazyLight and the Pulsar X2 CrazyLight are wireless gaming mice from the same lineup. The biggest difference between the two mice is their shape. The medium-sized variant of the X2N is significantly larger than the X2 and has a much more rounded center hump and a wider rear end. As a result, the X2N is slightly heavier than the X2.
The Endgame Gear XM2w 4k and the Pulsar X2N CrazyLight are wireless gaming mice. They both have shapes optimized for claw grips, but the Endgame Gear has a more aggressive rear hump, while the Pulsar has a more subtle curvature and higher overall profile. The Pulsar is significantly lighter, but has an open bottom plate that allows debris to enter the mouse, and has a smaller battery, resulting in shorter battery life. The Pulsar has a higher polling rate of 8000Hz, but this doesn't result in any meaningful performance differences.
