If you're looking for the best gaming mouse, you may not have considered a model with a built-in joystick. And with the introduction of the Asus ROG Chakram, it just got a little bigger.

My initial impression of the mouse with built-in joystick was due to the Lexip PU94; I'm curious how it compares to the Chakram, but that's a topic for another day.

Meanwhile, Asus provided an overview of the Chakram's specs and features: a wireless rodent that supports the Qi standard. On the wireless side, it can connect via RF (2.4 GHz) or Bluetooth (expect longer latency with Bluetooth, and Asus' joystick does not work with Bluetooth). For those who are "wired or dead," a USB cable is included.

The built-in joystick is the main attraction, which we will discuss later, but it is not the only interesting feature of this Chakram. The left and right clickers use Omron switches, which can be easily replaced by removing the magnetic cover and buttons. No screwdriver is needed. The same goes for installing the new switches. It is set up by a "proprietary push-fit switch socket".

"Replacing a switch is a matter of seconds, and you can easily install one that matches your preferred operating force and feedback, or replace a worn or broken switch to extend the life of your ROG Chakram," says Asus.

The optical sensor is adjustable from 100 to 16,000 dpi. Other specs include a maximum acceleration of 40 g and a maximum speed of 400 IPS.

Now back to the joystick. It operates in both analog and digital modes. In analog mode, it functions like a real joystick or thumbstick; according to Asus, this mode is "ideal for flight sims and racing games."

In digital mode, which Asus recommends for first-person shooters and battle royale games, the joystick becomes programmable in four directions (up, down, forward, back). In other words, it appears to be quite versatile.

Rather than take a one-size-fits-all approach, Asus has included both long and short joysticks that can be popped on and off with nubs embedded in the sides. A socket cover is also available for those who wish to ditch the joystick altogether for a flush finish.

While pricey, this could be an interesting product in the gaming mouse arena. After showing off the Chakram at gamescom last year, Asus says it will be available this month for ~$150.
