Question about Logitech G G910 Orion Spectrum

Unfortunately, I have to confirm many comments and am "reassured" that I am not the only one who has a problem with the doubling of characters at Logitech (...for me it is the letter "L" and a 2-3 year old G915...). With a cheap junk I would somehow understand this after 2 years, but with Logitech and the pharmacy prices such a thing has to work correctly for many years, at least as far as such basics are concerned.
