For the $80 (with shipping) that I spent, I'm pleasantly surprised at how good this mouse is. The weight on my copy is a little higher than advertised (closer to 60g with grip tape), which is a little disappointing, but it's still a very lightweight mouse. Clicks are crisp, and the tracking and glide feel very nice. Overall, a very appealing alternative to the Viper V3 Pro.
I will note that the web driver did not work out of the box on Linux; I had to employ the following steps to get it to work (credit to /u/USERNAME123_321 on Reddit for the original instructions):
Find your idVendor and idProduct with the command lsusb.
There will be two hex values after "ID", separated by a colon. These values represent the idVendor and idProduct, respectively.
In my case, it was Bus 005 Device 002: ID 373b:11d9 Compx Wireless mouse 8k dongle-L
su - (Switch to the root user)
Add a file to /etc/udev/rules.d
I've named it 50-usb-{name}.rules (e.g. 50-usb-atkmouse.rules)
The extension must be ".rules"
In that file add the following text, changing the values to yours:
KERNEL=="hidraw*", ATTRS{idVendor}=="idVendor", MODE="0666"
In my case, I wrote KERNEL=="hidraw*", ATTRS{idVendor}=="373b", MODE="0666"
This setting will give every user the authorization to read and write the HID devices manufactured by the specified vendor
Add your user to the input group, using the following command: usermod -a -G input (It will probably work fine without this step)
Reboot the system
