The Pulsar X2 CrazyLight is a wireless gaming mouse that continues Pulsar's X2 series. It shares the same shape as the Pulsar X2V2, but it's smaller in size and, true to its name, more lightweight. 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). 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
Despite being primarily designed for gaming, the Pulsar X2 CrazyLight is decent for work use. It has excellent build quality and connects wirelessly with its 2.4GHz receiver. You can program all its buttons using the downloadable configuration software. Unfortunately, it lacks Bluetooth connectivity and useful productivity features like a free scrolling mode or L/R scroll wheel inputs.
Excellent build quality.
Lightweight bottom plate design means the inside is open to dust and debris.
Small battery size helps reduce weight but means more frequent recharging.
The Pulsar X2 CrazyLight is outstanding for FPS gaming. It's extremely lightweight, making it easy to move around quickly and accurately. Its small symmetrical shape is well-suited for claw and fingertip grips if you have small or medium-sized hands. Performance-wise, it supports a wireless polling rate of 8000Hz and offers exceptionally low click and sensor latency, ideal for competitive play. In order to save weight, it has a fairly small battery, so you'll need to recharge it fairly often, especially when using higher polling rates. Additionally, its open baseplate design also helps save weight, but it leaves the interior of the mouse open to collecting dust and debris.

Differences Between Sizes And Variants
The Pulsar X2 CrazyLight is available in several colorways. We bought and tested a Uyuni White unit. Pulsar also releases many limited edition or regional colorways, but we've chosen to avoid including mention of them because, apart from the visual design of the shell, these "edition" models are identical to their base model counterparts. You can see a photo of our unit's label for reference.
This mouse is part of Pulsar's wider X2 series of lightweight wireless mice. However, the lineup includes some major differences between variants, making it extremely confusing to consider them as a single family.
In the table below, we've identified major differences between current X2 lineup models. 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. For the sake of clarity, we've intentionally excluded models in Pulsar's "eS" series, a subcategory of variants with other differences, such as aluminum scroll wheels and OLED screens.

Popular Mouse Comparisons
The Pulsar X2 CrazyLight is a lightweight gaming mouse in Pulsar's broader X2 lineup. It has the same size and shape as the Pulsar X2V2 Mini and X2V3 Mini but is significantly lighter and includes an 8K-capable receiver.
This mouse is aimed at competitive FPS players with small to medium hands who want the lightest possible option for fast, consistent movements. It's positioned at an upper mid-range price and compares most directly with the MCHOSE L7 Ultra, which has virtually the same shape and is only slightly heavier but much cheaper. Another close competitor is the Ninjutso Sora V2, which offers a similar shape and weight at a comparable cost if you purchase Ninjutso's 8K receiver separately. It's worth noting that one element that also makes the Pulsar stand out in this comparison is that it has an open baseplate design that helps further reduce its weight but leaves the interior more exposed to dust and debris.
Between these three mice, there are no meaningful performance differences using optimal settings, and although the MCHOSE may be the most compelling option due to its price, the CrazyLight has noticeably better build quality. The MCHOSE we tested suffered from some minor flaws, including slightly mushy post-travel on its switches and some flexing under moderate pressure on the top panel. Finally, the Pulsar may also appeal if you prefer its more distinctive colorway options, which stand out in a market where most mice are still limited to black or white.

The Pulsar X2 CrazyLight and the Logitech G PRO X SUPERLIGHT 2 are lightweight wireless mice designed for competitive FPS play. Both mice have outstanding performance. The Pulsar is smaller and noticeably lighter. It's also available in a wider range of color options. However, its open baseplate design leaves the internals more exposed to dust and debris. The Logitech, by comparison, is larger with a safer, more accommodating shape that suits a wider range of hand sizes and grips. It has a more conventional closed bottom for protection.
The Pulsar X2 CrazyLight and the Razer Viper V3 Pro are both lightweight wireless gaming mice aimed at competitive FPS players. Both deliver outstanding raw performance, and their symmetrical shapes make them well-suited for a claw or fingertip grip for small or medium-sized hands. The Pulsar is smaller and noticeably lighter. It also has a wider range of colorways available. The Razer, on the other hand, is slightly larger, especially in length. It has a solid baseplate design that protects the internals from dust and debris
The Pulsar X2V2 and the Pulsar X2 CrazyLight are lightweight FPS gaming mice that share the same symmetric shape, but the X2 CrazyLight is a bit smaller and lighter. It also features a newer sensor with improved performance and comes bundled with a receiver that supports polling rates up to 8000Hz. In addition, it's offered in a wider range of colorways. By comparison, the X2V2 supports up to 1000Hz polling out of the box and can reach a 4000Hz polling rate only with the purchase of a separate dongle.
The Pulsar X2 CrazyLight and MCHOSE L7 Ultra are lightweight wireless mice with virtually the same shape. Both perform exceptionally well, but the Pulsar is slightly smaller, with sturdier build quality and higher-grade pure PTFE feet that glide more smoothly on pads and desks. Its main drawback is the open baseplate, which helps reduce weight but leaves the interior exposed to dust and debris. By comparison, the MCHOSE is larger and slightly heavier. Unfortunately, it has lower-quality dyed PTFE feet that glide less smoothly and minor build issues, including slightly mushy primary clicks and some shell flex.
Test Results
This mouse has a straightforward look with minimal styling. It doesn't have any RGB lighting, but there's a CPI light indicator on the right side of the CPI button on the underside. You can customize the behavior of this light using the configuration software.
The baseplate of this mouse isn't a solid piece of plastic but a plastic frame that leaves open spaces, revealing the interior of the mouse. The 3D scanning tool we use has a limited ability to capture open cavities, so some of the interior spaces appear shallower than they are in reality. For comparison, you can see a photo of what the underside of this mouse looks like.
The Pulsar X2 CrazyLight has excellent build quality. Despite being extremely light, the plastic body feels very sturdy, and there's no noticeable creaking or flexibility on the body. If you press with enough pressure under the side buttons, you can actuate them unintentionally, but this is somewhat typical and isn't an issue you'll experience when using the mouse normally in-game. The main clicks are light and crisp throughout their travel, but they have a noticeable amount of post-travel. The scroll wheel is on the louder side with distinct steps, but it feels ever so slightly scratchy out of the box.
The coating has a smooth finish that may feel slightly slippery with completely dry hands, but it gains grip quickly with use, especially if your hands sweat a bit more while gaming. The Uyuni White colorway we tested shows dirt and scuffs fairly easily, while darker color options are likely less prone to visible marks.
The Pulsar X2 CrazyLight shares the same shape as the larger Pulsar X2V2 and is identical in size and shape to the Pulsar X2V2 Mini and Pulsar X2V3 Mini.
It has quite straight sides with only a small curvature near the front and back. The hump on top of the mouse is positioned slightly towards the rear with a fairly abrupt drop-off. The buttons are well-placed and easy to differentiate between, and the overall shape is best suited for a claw or fingertip grip for small or medium-sized hands.
The Pulsar X2 CrazyLight uses a 200mAh battery, which is smaller than the 300mAh unit in the Pulsar X2V2 and much smaller than the 500mAh battery in models like the MCHOSE L7 Ultra.
Pulsar doesn't provide battery life estimates on their product page. Based on capacity and polling rate, you can expect less than 10 hours of runtime at 8000Hz. At lower rates like 1000Hz or 2000Hz, battery life should extend significantly, ranging from several days to about a week, depending on usage.
This mouse's large feet have rounded edges and glide very easily on mousepads and desks with minimal resistance.
Pulsar also includes a set of 16 UHMWPE dot skates, which you may prefer using if you use a hard mousepad.
- USB-A to USB-C cable
- Wireless Receiver
- 16x dot skates (UHMWPE 6.6mm)
- Stickers
- User documentation
You can program all the buttons on this mouse except for the scroll up/down inputs and the CPI button on the underside.
The Pulsar X2 CrazyLight has superb click latency, providing an exceptionally responsive and consistent experience for gaming in any genre, at any competitive level.
We conducted this test with the lowest debounce setting of 0 ms, the maximum wired polling rate of 1000Hz, and the maximum wireless polling rate of 8000Hz. However, we've confirmed that setting different polling rate settings has no effect on click latency, only sensor latency, and this is becoming increasingly common on modern gaming mice.
This mouse's sensor reliably tracks your movements exceptionally well with virtually no speed variation.
The Pulsar X2 CrazyLight has extremely good sensor latency, making it well-suited for competitive gaming.
The above results are using optimized settings, with a wireless polling rate of 8000Hz with Motion Sync off.
We also performed supplementary testing at 4000Hz, 1000Hz, and 8000Hz with Motion Sync enabled.
We attempted to use the software's Turbo mode setting, but it didn't function correctly at the time of testing. In any case, we don't expect it to meaningfully affect our results. According to Pulsar, Turbo mode locks the sensor scan rate to 20K, which may provide benefits at lower CPI settings, though it comes at the cost of higher battery consumption. See the Configuration Software section for more details.
This mouse supports polling rates of 125Hz, 250Hz, 500Hz, and 1000Hz over both wired and wireless connections, and 2000Hz, 4000Hz, and 8000Hz when used wirelessly with the included wireless dongle.
The software allows you to adjust additional sensor settings, including Motion Sync and other performance settings. For more details, see the Configuration Software section.
The Pulsar X2 CrazyLight's mouse wheel has a grooved rubber surface. It uses a Pulsar Blue Encoder, which has pronounced step definition and is somewhat louder than average. On our unit, the steps felt a bit scratchy out of the box, though this may improve after a break-in period. The middle click gives satisfying tactile feedback and doesn’t require much force to actuate.
You can download the software from Pulsar's download page. The installer is only available through a Google Drive link, and it's too large for Google to scan for viruses. We didn't detect any malicious activity after downloading or running it, but this kind of distribution method is unusual.
That being said, the software is easy to navigate and well-organized. It's less bloated than software from larger manufacturers and offers a wide range of adjustments, including debounce time and sleep options.
You can also toggle Motion Sync, a setting that attempts to synchronize sensor data with USB polling events. This can make on-screen motion feel more consistent. We recommend trying this setting to see whether you prefer the feel with or without it, and use whichever option feels right to you. For details about the effect of this setting on performance, see the Sensor Latency section.
Unfortunately, some functions don't work reliably. Sleep settings, for example, frequently fail to save correctly. There's also a Turbo mode, which Pulsar’s software page describes as fixing the sensor to a 20K scan rate at the cost of higher power usage, but this feature is currently non-functional.
