Owners keep the MK4 as the printer they trust to run unattended and turn out clean parts, and they accept paying well above the competition for it.
Owners who had fought with older or cheaper machines describe the MK4 as the one that simply prints, with the load cell probe giving them enough confidence to leave it running while they are away. One owner keeps it as the primary machine for exactly that reason.
The price is a clear complaint. Owners put an assembled MK4 at several times the cost of rival printers with a similar feature set, and say that upgrading from an MK3 or from the base MK4 to the MK4S adds enough cost that they hesitate or buy a whole new machine instead.
Pick up to three. You get a page with just those, side by side, on the subjects owners raised.
What still pleases owners after the novelty passes is the sense that the machine does not need babysitting. The comparison people keep making is with an Ender 3 they had modified and fought with; next to that, the MK4 is described as the one that just works, and one owner repurposed the old printer as a spool holder. Not every account is spotless: one owner said a recalibration did not fix a problem.
The adjustment owners talk about most is the upgrade question, and they are divided on it. Some see the upgrade path as the reason Prusa costs what it does, pointing to the MK3 owners who could choose between several upgrade routes when the MK4 arrived. Others feel the path forward from the MK4 is poor value, since the kit to the newer Core One leaves much of the machine behind, and one owner chose a new Core One kit over upgrading the MK4 they already had. Owners also wonder whether newer belt and pressure advance features will come to the MK4S, but there are too few accounts on that to say.
The accounts that speak to how the printer holds up are positive on the whole: owners describe it as the machine they rely on day to day, with the load cell keeping first layers consistent. The one hardware problem described in detail was a nozzle leaking at the heat break on a new MK4, and that owner's real frustration was with support, where wait times ran over an hour and the chat dropped when they switched apps. Support accounts are divided: another owner praised Prusa for offering to cancel or add value after a price change, while a third was refused any discount after buying an MK3S+ shortly before the MK4 launched.
Long-term accounts are thin. Only a handful of owners spoke directly about print reliability, and most of the comments about this printer are about upgrade costs and paths rather than wear, failures, or repairs over years of use. We cannot say much yet about what breaks on an MK4 after long service.
Nothing with a clear majority yet. Owners who raised these subjects were split, or too few to judge.
Nothing has a clear majority against it yet. Counted from the owners who raised each subject, not from everyone. A subject is judged once at least 4 owners raise it.
The same owner, asked again at each point. Fills in as owners answer.
