This is a counterfeit Logitech G304 mouse. It shows up as a Sharkoon device in a hardware scan.
It is not recognised by the Logitech software. Because of this, none of the settings of the mouse can be changed. DPI can not be changed. Buttons can not be programmed.
On top of this, the item took a very long time to arrive and the box was squashed. It arrived from China and not from Western Australia.
Seller refused refund the money and ebay had to step in.
