Condition

AS STATED BY SELLERS
Used / refurbished1
Not stated7

Most industrial listings do not state condition — treat unstated as unknown, not as new. Across 8 comparable parts in SLC 500 CPUs, used and refurbished units list at 127% of new — condition is not a reliable discount signal for industrial parts, because refurbished stock from trade houses carries warranty and test reports.
