Can you build a wireless gaming mouse that weighs less than a chicken egg? Pulsar pushes the limits with its X2 Crazylight Medium, an FPS-focused mouse that weighs just 39 grams.

In this review, we’ll explore whether this featherlight wonder delivers in real-world gameplay.

Pulsar X2 Crazylight Medium: Design and features

The Pulsar X2 Crazylight Medium lives up to its name: the mouse only weighs around 39 grams, which is almost unbelievably light for a wireless mouse. By comparison, even ultra-light competitors like Logitech’s G Pro X Superlight 2 at around 60 grams or Razer’s Viper V3 Pro at 54 grams are about 20 grams heavier. Pulsar achieves this weight through careful internal weight savings.

The result? The Pulsar X2 Crazylight Medium feels surprisingly stable despite its lightweight design. The housing neither creaks nor rattles during everyday use, and the buttons sit firmly without any annoying wobble.

The surface is matte and smooth, which makes for a pleasant feel, but it can become a little slippery with very sweaty hands. Optional grip tapes help here. It would have been a nice touch if the manufacturer had included them by default.

The shape and dimensions of the Pulsar X2 Crazylight Medium follow the popular Pulsar X2 design in a slightly shrunken version. The Medium model is around 12 centimeters long, 6.3 centimeters wide, and has a flat, symmetrical body.

This allows the mouse to sit comfortably in the hand, especially for claw-grip and fingertip players. Those with medium-sized or small hands will find the low, wide shape extremely comfortable. The mouse doesn’t completely fill the hand, but it provides plenty of control for quick movements.

On the other hand, the Pulsar X2 Crazylight Medium may feel a little small for larger hands. Pulsar also offers a large and a mini version.

Pulsar X2 Crazylight Medium: High-end sensor

Despite its minimalist design, Pulsar doesn’t skimp on top-level technology. At the core of the mouse is Pulsar’s exclusive XS-1 sensor, which is based on Pixart’s PAW9350. This optical sensor supports an impressive 32,000 DPI resolution, 750 IPS, and 50 G acceleration. That’s more than enough for extreme sensitivity settings or even 360-degree spin shots in shooters.

Pulsar also offers an optional polling rate of 8000 Hz (8 kHz) via 2.4 GHz radio. By default, the mouse transmits at 1000 Hz, which is already very responsive. However, if you want every possible millisecond and have the right hardware, you can increase the polling rate up to 8000 Hz using a separately sold dongle.

Currently, only a few mice like the Logitech G Pro X Superlight 2 (Lightspeed 2) support such a higher wireless rate out of the box, without replacing the receiver. In practice, the difference is only noticeable in professional esports or with high FPS displays. For most users, 1000 Hz is preferable given the potential side effects… but more on than later!

It’s especially pleasing that Pulsar uses specially developed optical switches, which should last up to 100 million clicks and is designed to prevent double-click problems. The click feel and mouse wheel are subjectively different from mechanical switches. In the case of the Pulsar X2 Crazylight Medium, we noticed slightly less “rich” feedback, but clearly defined scroll steps. This is largely a matter of taste, though.

Pulsar X2 Crazylight Medium: Tiny battery

Speaking of side effects, the radical lightweight construction does have its drawbacks. In order to reduce the weight so drastically, Pulsar has cut corners, especially with the battery and the base of the housing. The battery is tiny.

Pulsar itself claims a battery life of up to 65 hours, but this figure is probably only valid under the best conditions. In everyday use, you’ll have to charge the mouse more often than usual, especially when using high polling rates. The battery drains rapidly, sometimes after less than 10 hours of continuous use.

In 1000 Hz mode, the mouse lasts a few days depending on the usage profile. In our experience, it lasted around five to seven days with average gaming time. This result is fine, but it’s significantly shorter than other competitors. Logitech’s Superlight 2, for example, lasts up to 90 hours.

The second compromise concerns the underside. The X2 CrazyLight has a skeletonized base plate to shave off some weight. In concrete terms, this means that, in addition to the PTFE gliding feet (Pulsar supplies smaller “dot” skates in the package), there are recesses through which you can see inside–even the battery is partially exposed.

While this design saves on weight, it also exposes the electronics to dust and dirt. This isn’t a major problem in a clean gaming environment, but we’d recommend not using the mouse on dirty or crumbly surfaces.

In more unusual scenarios, you could theoretically push the battery through the openings, but this is unlikely to happen in normal use, unless you finger the underside of the mouse with sharp objects. Overall, we find the compromise acceptable. Most gamers will appreciate the weight advantage more than a fully closed base plate.

Pulsar X2 Crazylight Medium: Performance

In FPS use, the Pulsar X2 Crazylight Medium delivers immediate, almost weightless handling. Fast flick shots are precise, and changes in direction feel effortless thanks to the mouse’s low weight.

The combination of a high-precision sensor and optical switches creates a direct, responsive gaming experience, which is especially noticeable in titles like Valorant or Counter Strike. You also benefit from the precise fine control in tactical shooters, as even slow, deliberate movements are tracked accurately.

Away from shooters, the mouse still performs reliably. In MOBAs like League of Legends, you benefit from the fast responsiveness of the buttons, although the limited number of additional buttons may be a drawback for some folks.

In action RPGs like Diablo, the mouse feels comfortable even during longer sessions thanks to its lightweight casing. The precise tracking also makes it well suited for creative tasks, such as image cropping or detailed work in graphics programs.

The symmetrical shape supports smooth control, making long office or browsing sessions comfortable and effortless.
