Most of the mice I've had so far were Logitechs, including my first one (the good old Pilot Mouse). What they (almost) all had in common was that the left mouse button had hardly any resistance within a few months, which is of course nonsense for a mouse. For the first time, I have a new problem: I've been using a Logitech G402 for a few years (after all!) - and its
right mouse button is now weak.
I seriously consider getting a SteelSeries mouse next, hoping that the modern "gaming" mice will be more resistant.
