What is covered under the Xros Mini warranty and how long does it last?

Vaporesso offers a limited 90-day warranty from the date of purchase, requiring valid proof of purchase such as an invoice or receipt. The warranty does not cover damage caused by misuse, human damage, opened consumable items (such as cartridges, coils, or e-liquids), or any hardware that has been cracked, dismantled, or modified.
