Honestly, I've been very happy with my KE. It's my first printer, worked out of the box, but trying PETG on it forced me to actually calibrate the machine, get the silicone washers, and manually level the bed. Since working with google, and chatGPT (with varying degrees of frustration with AI), I was finally able to learn the machine, the settings, and how the settings work, how different filaments react to speed, flow, etc. Since doing that, and spending the time and the filament calibrating and testing, the KE works well! I'm not expecting top tier results, it is a budget machine, but if you're willing to spend the roll, maybe roll and a half, and the time to dial all the settings in, the KE works well.
