With mice sensors getting so ludicrously high-spec’d, some competitive gaming mouse brands are instead trying to make the shell as light as possible. Lighter = speedier. And Pulsar is finally joining the uber-lightweight mouse trend, with a 29 gram gaming mouse that is, well, half of a mouse.
Effectively, the new X2F CrazyLight is just the front half of a gaming mouse, including the sensors, switches, and battery. Pulsar is not the first to cut a gaming mouse in half (in fact, the G-Wolves HSK Pro V2.0 has been around for a while and is just 26.8 g).
It’s not even the first very light gaming mouse from Pulsar, with the X2 CrazyLight Mini being 35 g, but it is the lightest ever Pulsar mouse, to my knowledge. And it manages to get that weight without going for the honeycomb shell that many other lightweight competitors go for.

According to Pulsar, the new X2F comes kitted with Pulsar’s new SX2 sensor, which we don’t currently have the stats for. The previous generation XS1 has a DPI of up to 32,000, a max speed of 750 IPS, and acceleration of 50 G. This is the sensor our Jacob Fox had his mitts on when he reviewed the X2 CrazyLight Medium and X3 Crazylight Mini. It also supports up to 8,000 Hz polling. I would assume the XS2 ups some of those stats.
For context, the Razer Viper V4 Pro, which we consider to be the best gaming mouse right now, has Razer’s latest Focus Pro sensor and offers 50,000 DPI, with a max speed of 930 IPS, and acceleration of 90 G.

Alternatively, we think the Logitech G Pro X2 Superstrike is the best competitive mouse right now, and its Hero 2 sensor offers a DPI of 44,000, a max speed of 888 IPS, and a max acceleration of 88 G.
Whether or not the X2F CrazyLight will be the best competitive mouse after its release on September 28 will likely be a combination of how good the sensor is, how well balanced the weight is, and, of course, its price. Unfortunately, we don’t have information on any of those yet. Also, even within the competitive mouse scene, it’s sure to be pretty niche, since you have to use a fully fingertipped grip to use these kinds of mice.
We haven’t got hands-on, so it’s hard to say much more, but the only critique I could levy from looks (other than ‘where’s the rest of the mouse?’) is that you can already see the 210 mA battery, so it’s a shame it’s not hot swappable. A hot-swappable battery could allow for a smaller battery in the device itself, further reducing the weight, and it’s just a great way of staying charged at all times. Though that would presumably add on extra weight, which might defeat the purpose for this kind of mouse.
The notion of chopping off half of your gaming mouse to improve speed definitely feels a bit niche to me, but the fact that multiple companies are doing it implies there are many more competitively minded people than I otherwise thought. Let’s just hope they aren’t in my games. I prefer the easy opponents I’m currently being put up against.
