So I think this mouse has the classic Logitech double clicking issue, when you left click it also right clicks. This can be circumvented by disabling the right click in g hub software but I think to fix it properly you will need a switch replacement (under £10 and a soldering kit) but I’m not good enough with my hands to do it. Sometimes the side button closest to the back will also double click but it’s not permanent, only happens occasionally, but other than those 2 issues that the mouse works (as best it can with these issues) Full original box with replacement skates and dongle (frayed wire but still works)
