Czech inventor, Josef Prusa, takes great pains to preface the name of each model with the word "Original" (e.g this is an "Original i3 MK3S"). Dozens of Chinese companies have copied his i3 machines and sell them for 1/3 to 1/2 the price. But buyers must deal with no support, disconnects between absurdly poor instruction manuals and parts, poor quality parts, parts that do not fit or work, no wonder that a large percentage are never able to complete the assembly. This printer, by contrast, has a LEGO-quality instruction manual and lots of online support. It also has auto bed levelling (this is a huge factor), much better cable routing, automatic filament insert, removable flexible bed, has its own slicing software, it prints faster, is quieter, does not break down all the time and print quality is much better (note the closeup: less than 1mm thickness, yet highly precise). You can even pull the plug out of the wall during a print and it will continue after reconnect! And its updates its software through the slicer software (super important to new).
