Customer support is abysmal
Customer support is abysmal. My X4 Plus S1 has been completely dead for 5 weeks. I receive completely unhelpful responses every 3-4 days. They have sent me zero parts, or replacement (printer is 2 months old). They have asked me to fill out the exact same form 3 times. They want the user to do all of the work. They wanted me to reflash the EMMC chip, which requires a special usb adapter,nwhich they didn't send me. Then they told me I need a new mainboard, And after a week of no responses, they asked me to fill out the excel form AGAIN. They also expect me to replace the mainboard myself. The case specifically says if I open it, my warranty is void. And ALL of the connectors to the board are GLUED.
