Needed to return the item as it was incompatible with my charger. That wasn’t the issue, however. Return address was supplied in Chinese characters, yet item was dispatched from UK. Pressed for UK return address and offered small refund to keep item. When I advised that I had no use for the item and advised I would return it, I was offered a higher refund. In the meantime l, I’d posted the item back. Had to chase refund payment, ended up out of pocket, and whole process was hassle.
