I purchased a Qidi I-Fast printer from MachineShark in 2023. I received it quickly. It came with quick-start instructions to make setup easy. Now that I have had the printer for over a year, I want to tell people about Qidi's amazing customer support for my printer after hundreds of hours of successful projects I have printed on the machine. Qidi has helped tremendously on my learning path of 3d printing (i knew nothing about 3d printing when I bought it). They have supplied comprehensive instructions when I have questions about hardware and software. They respond quickly to emails, sometimes sending detailed videos to explain. I have to say, I can't think of any manufacturer that has given me such great support.
