DPI
The Venus has an advertised 16,400 DPI or double that of its closest competition. Since Logitech and Razer use similar Avago sensors this is most likely tuned by software. That being said DPI above 4,000, in my opinion, is somewhat gimmicky and not worth resting your purchasing decision on.

Programmable LED Lights

Another nice feature of the Venus are its programmable LED lights which allow you to pick one of 16 million colors as well as the brightness and breadth of the lights. For the 5 pre-customized profiles you can go between yellow, green, blue, purple and red and have the entire mouse light up in those colors. If you customize the light color, then the scroll wheel will remain the color of whatever pre-customized profile you used.

Another design feature the Venus comes with that its competition doesn’t is its small thumb rest. While this rest could be extended to improve its usefulness it is kind of nice for preventing misclicks on the thumb grid.
