All Vector lighters are backed up by Vector-KGM’s famous No Proof Warranty. No Proof Warranty means just that. You are not required to provide a proof of purchase in order to receive warranty services on any malfunctioning Vector lighters. It’s a hassle free, no questions asked, warranty service program. It’s Vector-KGM’s way of showing appreciation and commitment to its customers. Vector-KGM is the last remaining company with an actual in-house warranty service department, with actual lighter-specialist technicians who can perform repair services on the lighters. Our industry leading turn-around time of 1-2 weeks truly sets Vector-KGM apart from other so-called lighter companies without any in-house QC and service departments.
