This is a Korean proxy. Items sold non-returnable and non-refundable. Warranty is 1 year provided by the manufacturer, however, buyer would need to ship the product back to Korea for any repairs. All shipping fees will be paid by buyer.
Please email me if you want me to open the box before shipping to check for potential DOA or keep the box sealed. I do not accept DOA as reasons for refund/return if you had opted for sealed box.
