Razer Naga mechanical version. There's no misclicking, the buttons are very distinctive.
The old version was prone to double-clicking after a while, not so sure this newer one is (had it over 2 years now, extreme daily usage), and honestly even if it did, I'd just buy another. Every other brand has their issues as well, the reason it's so well-known is because SO many people use the Naga. You'll obviously see more comments on something more people use. There's nothing competing with it in terms of number of buttons and comfort (tried the G600 or whichever the Logitech one is, but it's just awkward to hold compared with the ring-finger click).
