All of the G502's with the Hero sensor are pretty much the same.Dan,
Thank you for a very comprehensive and helpful reply, though sadly not the one I was hoping for. Like you, I like the ergonomics of the Logitech mice, but also like you, I find they wear out far too quickly. I was hoping the Razer mice would be longer-lasting. They'd need to be to justify their high price. I have a Razer DeathAdder V2, which was reasonably priced and has lasted well so far. It's a good gaming mouse (I use a claw grip for gaming) but I dislike it as an office mouse (I use a palm grip for office work). I was attracted to the Lunar Artefacts mouse because it's designed to be repairable, but it seems to have too many other problems. I'm fed up of buying disposable mice. I've been hoping that someone will create the mouse equivalent of a mechanical keyboard (I love my Code Keyboard). In the meantime, it sounds like the choice is to either buy something like a Logitech G502 Hero because it's cheap enough to replace when it wears out or buy something like a Razer Naga and hope that it lasts long enough to justify the considerable extra cost. Have you noticed any significant differences between the different versions of the G502 (other than wired vs wireless operation), or should I go for the G502 Hero because it's the cheapest?
