I have purchased a fiire 12TB and a prestige lite with usb ir transceiver, below is my experience.
Experience was decent. My order was placed Nov 9th and was shipped Nov 24th. All but 1 item was originally shipped (USB IR Transceiver). I engaged support regarding this about and 1 faulty 500GB hard drive on 11/30. The UIRT and hard drive has been replaced as of 12/8.
I would purchase from fiire again.
