Yeah, I did the printer as a hobby thing when I built my first reprap. It was fun, and I learned a ton, but the state of the art in 2014 just wasn't there for low-end machines to be reliable. I replaced it with a prusa in 2019,and I have had zero issues at all with it. The only print failures I've had were either due to part design or bad filament (pla stored in a humid garage). I've been super impressed with the quality of the machine, and have printed some fairly challenging parts. Plus, the whole machine is open and hackable. I didn't really even consider other printers, since I wanted to support prusa and what they have done for the community. Although I have used a friend's ender 3, and I was pretty impressed with the quality for the price.
