In most cases, you will get a brand-new sealed unit for a product that's dead on arrival. But if you have bought an unboxed or demo unit, you will receive an unboxed/demo unit as a replacement. In case a replacement of the product or its color variant is unavailable, you will be given store credit.
However, in the case of products where only one part is defective, we will replace the same (whenever possible). Eg. If the cable alone is faulty, that alone will be replaced.
Sometimes the spares or replaceable parts have to be procured from the brand and that can take a little longer depending on the product and brand. A more realistic timeline will be given to you after getting an update from the brand, though we will try to expedite the process.
