Warranty Cover

New items carry the manufacturer's warranty. Tengaikoko handles the claim itself, starting with our repair partner. You do not ship the item back to the United States, and you do not agree a separate freight charge with us.

Open-box and pre-owned units sold by Tengaikoko come with a limited Tengaikoko warranty (ask us for the cover period before you buy) covering functional faults that weren't disclosed in the listing. It doesn't cover accidental damage, liquid damage, unauthorised repairs or normal battery wear.

We record every unit's IMEI or serial number against your order. Warranty claims are checked against that record, so you don't need to keep a paper receipt. Just give your order number.

Open a ticket on Support with your order number, the IMEI/serial and a short video of the fault. We'll reply as quickly as we can.
