A quote from the article:
The Scimitar RGB Elite is the newest entry in Corsair's MMO/MOBA gaming mice line. It still features the same patented 12-button key-slider side panel and the same shape and shell, but comes with an upgraded sensor (PMW3391) as well as improved components and materials.Corsair Scimitar RGB Elite Mouse Review
