Condition

AS STATED BY SELLERS
Used / refurbished3
Not stated6

Most industrial listings do not state condition — treat unstated as unknown, not as new. Across 80 comparable parts in SIMATIC S7, used and refurbished units list at 96% of new — condition is not a reliable discount signal for industrial parts, because refurbished stock from trade houses carries warranty and test reports.
