I was very pleased with the overall experience.

I placed two orders with SQRL on 7/13. I sent an email requesting a change in the delivery address on 7/13 to the support email address in the order confirmation email and received confirmation of an open ticket within a few minutes. On 7/17 I received a status update email, and then on 7/19 an email confirming my address change had been made and the first order was linked to my account that was created when placing the second order.

If you have issues, make contact and then be patient and let the support process happen. No complaints here.
