Today I got my K1 directly from Galaxus.
Still has the old HotEnd!
Special offer for the replacement K1 Power Boost Kit Plus at Creality has expired.
Kit also no longer available :-(
I won't keep it like this after all the experiences I read in the forums.

You can E-mail them directly at event@creality.com That is the address I used for the kit discount confirmation.
You can call Creality directly at +86 755 85234565

No, there is a process: You have to email a picture of the serial number on the white sticker next to the power cord and your receipt to event@creality.com (or something similar, check reddit.com) in the subject line write "purchase proof". Then post a picture on a social media site with "K1 Moments"(or something similar, check Reddit.com). Creality will E-mail you a code(B1K1 or similar, again check Reddit.com) Then wait 48 hours. Then when you apply the code at https://www.creality.com/pages...
https://www.reddit.com/r...

Edit- Seems like it might be too late: https://www.creality.com/pages...

I help this helps

When I got it, it did not have the kit with it.

No, it has to be ordered separately.
