I've gigged it intensively since October 2018, except for the lockdown, of course. We do a lot of outdoor gigs here in SoCal, and that takes its toll on your equipment in terms of dirt and bugs. For the most part it's fine, really, but I have noticed some inconsistencies creeping in on the keys, occasionally a note not triggering, or at the incorrect velocity etc. Nothing too egregious, but it's there.
At this point I'm not too worried about it, but it's something I keep an eye on. The same goes for my 2016 Korg Krome 73, which is definitely in worse shape. I view both instruments as disposables/write-offs, as in I don't think I'd bother fixing/repairing them. Just get rid of them when reliability fails. It's different for my Fantom X7. That one I will continue to patch up for as long as I can.
