Software

The Impulse Pro uses a standard software driver that comes with such ODM mice (even the executable file is called OemDrv.exe), but it's a very usable driver still. It's lightweight as it takes up less than 5 MB of disk space and consumes less than 17 MB of memory in my configuration. As for its design, it leaves something to be desired, but I can forgive that at this price point.

The main page consists of the button layout, where you can bind pretty much anything to the nine fully programmable buttons. You can switch between left-handed and right-handed modes as well, and access the profile options or create a number of different ones, import and export them, and link them to specific program launches. Pretty much the same applies to macros, and there's an option for batch exporting and importing as well. Macros have their own tab that can be accessed at the very top of the software's main window. The Sensitivity tab has the CPI settings—you can have a maximum of six active levels, but you can also remove them if you would like to have less. Each of these levels has a customizable color next to it, and the mouse lights up for a few seconds accordingly after the CPI level is set. The LED page naturally contains the RGB customization options I will touch on more in the next section. Lastly, the Parameter tab contains all the OS-related settings and the polling rate. The program automatically ticks the Improve pointer precision option, which I'd highly suggest turning off since it adds acceleration.

Once you've set everything up, feel free to remove the software as the mouse has on-board memory for the settings, including the macros.

Lighting

A lot of different RGB lighting effects are available for the Impulse Pro, which has three different zones that light up according to the settings—these zones are not individually controllable, though. The effects are pretty much the "usual", and while implemented well, I've seen better. As for the brightness, the lighting could be brighter by today's standards, but I honestly don't mind if the mouse doesn't poke my eyes out with its flashing lighting effects.

Here's a demonstration video of some of the lighting effects:
