This model with a solid black trackball and all black buttons/housing, is probably their most minimal and sleek version, without any LEDs, it'll blend in covertly with the most modern PC desk layouts. I swear by these mice - been using them for many years, and while they do sometimes need to be opened and cleaned (they collect gunk in the rollers occasionally due to the nature of a top-mounted trackball itself, or rather, people's gunky fingers) they are built to endure drops and travelling. With built in macros to contol DPI (cycling by pressing MMB+RMB), the pointer control feels very precise, and trackball mice like this are great because once you have aligned your pointer over the desired target, you can take your hand away (the pointer wont move, even if someone moves the table), and simply press the LMB when youre ready to trigger - which is great for people that do editing, live production or and other types of media composing, where timing is an important factor. Trackball mice may not be for everyone (I can even admit this might not be the absolute best for twitch gaming genres like first person shooters), but for professional workplace-style productivity, or media production, theres really nothing better.
