Logitech make the finest peripherals in the game, hands down. This is no different. Any heavy excel users, audio technicians, video editors and multitaskers - Logitech's flagship productivity mouse is the only choice as far as I am concerned. This mouse would be a below average choice for gaming so if that's your use case I'd go elsewhere. Not that you won't be able to play games (on the windows version with the I closed 2.4GHz unifying reciever that is, Bluetooth is a huge no go) but it'll put you at a disadvantage in games.I bought the Mac version because it's being used for my work from home office setup and all of my gear is mac. On the off chance that there was some slight compatibility optimisation with this version I didn't want to pick up the original just for added dongle support if the Bluetooth performance could be compromised at all - I have read stories of people with choppy Bluetooth issues on the original when paired with mac which I have not experienced at all, but could also have been fixed with firmware updates since then to be fair. My employer also has a zero RF policy for security reasons so I wouldn't be able to use the unifying reciever even if I wanted to, Bluetooth is my only choice.Do I wish it had a 1000Hz polling rate? Yes - but this would probably significantly diminish battery life. The polling rate is fine for what I am doing, it's more a quality of life feature that I have become used to on my windows desktop and the difference is noticable to me. It's so far outweighed by all of this mouse's pros that I'm not bothered by it at all.The left and right click are extremely satisfying and crisp, the mouse wheel click is one of the most premium feeling and sounding I've ever felt. Build quality is exceptional. I like that the space grey finish matches all my other maccessories ( ;D ) but the colour isn't a selling point for me really. Weight and ergos are great for me and the gesture button lets me perform magic mouse type functions without having to use a magic mouse which is as ergonomic as a toaster.Whichever version you're looking to get, just buy it and get it over with. Think about how much you use your mouse every day, the return on investment is overwhelming considering the hours vs dollars and you'll be more productive and motivated to do more with proper quality tools.
