My original ticket? It mentioned that I had already tried the mouse on 3 different computers (windows desktop, macos macbook, and linux minipc) and all displayed the same behavior. So far Logitech's support has replied exactly one time and they did not even bother to read my ticket, they just sent the standard canned response of 'try setting the double click speed in Windows.' 'Make sure to try it on another computer' 'make a video of you clicking on this web page designed to detect double-click events'. I have owned the mouse less than 1 year and it has a 2 year warranty. Well, my MX518 Gaming has started doubleclicking in the past month or so. Around a year ago I bought a Logitech MX518 Gaming because I saw the LTT video for it and my current MX518 had been going strong for ~5 years, but it was showing signs of age.
