Warranty Claims for Quality-Related Issues

For quality-related warranty claims, items will be replaced with a factory refurbished model of equal value when available, otherwise, a new item will be sent. In situations where a replacement is not an available or preferred option, XINCOL will offer a partial refund according to the usage time of the device.

Warranties on all replacements follow the same warranty timeframe of the original defective item, or 3 months after being replaced, whichever is longer. Warranties on products are void after having been fully refunded.
