Welcome to Geekhack!
My first modern mechanical keyboard was a Ducky Shine. it is still going strong.
Now I have three Duckys.
Somewhere along the line I managed to get a QFR and also a QFS.
All those keyboards are still going strong, none has exhibited any fault at all!
Except for my second Ducky with MX blues, where two switches did not click consistently, but mashing those switches a few thousand times "wore them in" and now they are virtually indistinguishable from the rest of the keyboard.
