Frequently Asked Questions

What does "refurbished" mean at Refubly?

Every device is fully tested against a 32-point checklist, cleaned, and any failing part is replaced before it is listed. The cosmetic grade is stated on the listing, so you know what the chassis looks like before you buy.

What warranty do I get?

Every Refubly device comes with a 12-month warranty from the day it is delivered, covering hardware faults under normal use. Physical, liquid or accidental damage is not covered, and neither is the gradual loss of battery capacity with age.

Can I return it if it is not right?

Yes. You can return it within 7 days of delivery for a full refund to the method you paid with — for any reason, as long as it comes back unused and complete. If it arrives faulty or not as described, tell us within 7 days and we will replace it or refund it.

Is it safe to buy refurbished?

Every unit is wiped, reinstalled with a genuine operating system and function-tested before dispatch. You get the same warranty, invoice and support you would expect from a new purchase.

How long does delivery take?

Orders are dispatched after a final quality recheck. You will get a tracking link by email and text as soon as the courier collects your parcel.

Do I get an invoice?

Yes. A tax invoice (a GST invoice in India) is created for every order and can be downloaded from the order page in your account as soon as payment is confirmed.
