Quick resolution to wrong item during holidays!
They've always been responsive and make a great product, but when I received my order and found one item was different from what I ordered, they responded quickly (especially considering it was during the holiday season) to my email and sent me the item I had actually ordered ASAP. I had more trouble with my email glitching out when I tried to reply than I had getting my desired item. And I didn't need to send the incorrect item back or anything! I feel like this is the ideal interaction for this kind of situation.
