Very disappointing experience.
I emailed Giztop on the same day I placed my order for the Oppo Find X9 Ultra and specifically asked them not to use UPS, as UPS performs very poorly where I live while DHL, FedEx, and other couriers work fine. Customer support replied and told me that shipments to Europe are normally sent with FedEx. Despite this, my order was still shipped with UPS, completely ignoring my request. To make matters worse, one week after placing the order, UPS still had not even received the package. The advertised shipping times are clearly misleading. Customer support responds to emails, but it feels like they do not actually read or act on customer requests. This was my first order with Giztop, and I regret choosing them. In hindsight, I should have ordered from Amazon. It may have cost around €100 more, but I would likely have had no issues and already received my package by now.
