I purchased a K1 Max directly from Creality in October 2024.

This was well after the K1 Max had recieved the K1C upgrades. People had been getting K1 Max units with the small X/Y pulleys and upgrade hot end for MONTHS.

I bought it directly from Creality expecting to get a current revision.

I received a rev1 unit. It had signs of use. I asked Creality to replace it with the current revision and they decline.

It never really printed right. Using their filament and their slicer about 40% of the prints would fail. They kept dragging me along for weeks. I assume this was to push me out of the return window.

They literally never one entertained my suggestion of returning.

Until I call my credit card company. VISA said to box it up, email them one last time demanding a return label for a full refund, and if they did not give me one, VISA would do a charge back.

Whilst boxing it up I noticed another shipping label from before the K1C was released.

So they had absolutely sold me a unit that was not brand new.

Now I have a Sovol SV08 and if I was looking for a new printer I would be looking at the Snapmaker U1
