Corsair K55 RGB PRO Gaming Keyboard

This is a follow up review of the Corsair // K55 gaming keyboard, first reviewed on 28 Aug 2021 – After daily use since purchase, I got used to the fact that all keys which required a shift to get an alternate character (like 1; ! 5; % etc) were upside down on the actual keyboard and it hasn't presented with much of a problem. What has happened though which is more disturbing is that certain keys have developed a 'bounce'. That is, they print a number of times with a single key-press. The keys doing this are the 'a' and the 'f' on the alpha keyboard and the '9' on the numeric keyboard. This is a major problem as I don't always visually check what I have typed. It may be perculiar to my keyboard or it may occur across the range.
