This is an open-box unit: the retail packaging was opened, but the product was powered on and verified working before listing.
Open-box means the box was opened only — a customer return, an inspection unboxing, or damaged outer packaging. Condition can vary from unit to unit, so each is graded (A1, A2, A3) and priced to match.
Final sale:open-box items aren’t eligible for return or exchange for change of mind — except items that arrive damaged, dead-on-arrival, or wrong. See our final-sale policy.
