Is it possible to Drag-Click with this mouse?

Polling rate is the frequency at which the mouse position is transmitted to the PC. A higher frequency means the position of the mouse will be transmitted more often. Essentially, a high polling rate means for a higher accuracy in fast paced situations.


What is Debounce Time?

Debounce time is the amount of time that must pass before the second press of the switch will be registered. In other words, debounce time is the minimum time between switch presses. In some occasions, a low debounce time can be beneficial for gamers, as they could spam inputs for a competitive advantage. This is most notable for Minecraft, and mods like bed wars.

Our Fantech software allows you to customize settings such as scrolling speed, DPI, RGB lighting, macros and more. In some models, advanced settings like polling rate, angle snapping, and debounce time can be set too.

Can the mouse be used with a USB hub?

While a gaming mouse, as it is USB, can be connected to a USB hub, we generally suggest not to do this. This is due to how a USB hub doesn’t provide a direct connection between the mouse and the computer. To ensure a stable and precise communication between your mouse and the computer, it is important to directly connect it, as to avoid errors in the signal.

Also known as “Lift-Off Distance”, refers to the distance at which the sensor on your gaming mouse stops tracking mouse movements. This is important during gaming, as you will need to frequently pick up your mouse to reposition it on the mouse pad. With a high LOD, the sensor will keep tracking while you’re repositioning, which will cause your tracking to be inaccurate.

Are the Included Skates for Helios XD3V2 Good? 

The included mouse skates are made of pure PTFE, and will need to be “broken in” for users to experience the full performance. Typically, after a few gaming sessions, the skates will be a little more slippery than out of the box. This is normal and is the intended design of the mouse skate to ensure it can be properly transported without falling off of the mouse.

Such damages are not covered by warranty, which is why we explicitly suggest charging the mouse with the supplied cable and by directly connecting it to your PC.


Can I use the mouse without a dongle?

The Helios XD3V2 is not a Bluetooth mouse, and therefore requires the USB 2.4ghz dongle to connect to the computer for wireless connectivity. If you wish to use the mouse in wired mode, please use the supplied USB cable to connect it.
