Less than regular typing usage for two years (my main kbd has been another 70% layout; this one was used as sub). All functional and in good condition, with its original USB-A wireless knob. Box & manual are no long with it. If it had a cable I might have lost it and will substitute with a generic one.
This is the original keycap set, which apparently isn't too strong. Regions around home row is a bit shiny from normal usage. It's comfy to type on, no issues for me whatsoever. I don't know if it's suitable for gaming (which is its marketed purpose).
