I have not purchased this specific model YET - but I will be doing that shortly.  I am typing this one on a KINGDEL industrial computer I purchased in April 2018.  Except for power interruptions caused by storms, it has run continuously for 6 years.  Yep, I turn it on and leave it on.  Only reason I am buying another one is this one isn't able to support Windows 11.  I need W-11 to do some specific tasks.This one will continue to soldier on for as long as it last.  I will transition to a newer KINGDEL, but old faithful will be close by and ready to step in if needed.
