A bit about this kit: Overall, I've found the quality is near-perfect. I use 2 Original MK3S printers at work on a daily basis, and this kit is essentially the same printer. I was concerned with drive gears being bad, linear bearings being low-quality or the filament not sticking to the included PEI. None of that was the case here. It is worth noting however, the square nuts in the kits are not the same quality, and not quite the same dimensions as the one with the original, and hence they have some difficulty fitting in the parts. This can be mitigated by either hot-pressing the nuts or "upsizing" the holes with a flat screwdriver. The filament sensor included does not work with the newest firmware, quick googling revealed it to be the old version, a replacement does not cost a lot though. The original heatbreak is a full-metal part, while the one included with the kit is a PTFE lined heatbreak. I am definitely satisfied with this printer.
One needs to exchange the Heatbreak to an all metal one. The clone is shipped with a Teflon liner. Additionally exchanged the belts to other ones, as the supplied belt were wrinkled a bit. But anyways, quickly delivered within the EU and great print results out of the box. The package also includes enough spares. All in all a great deal.
