Terrible software, mouse scroll is laggy and annoying. One big scroll down a page, then scrolling back up bugs out allowing for small buggy scrolling. Or sometimes, causing it to stop scrolling at all. I found other people are having the same issue. Please see the following video from 0s - around 9s. Just before this person rocks the mouse back and forth. Its this scrolling issue which is tipping me over the edge to send it back. https://www.youtube.com/watch?v=J0bQmfUviVo
