This is the S, upgraded version, of the CR-10, which has the filament detector and the dual Z-axis screws. I don't think anyone other than the annoying to deal with companies, gearbest, lightinthebox, has had this for a price like this. Deal is already something like 70% claimed and goes for another 2+hours.
Price is 479.20 w/ FSSS or Prime shipping and maybe tax.
Also note that this is the HICTOP version, not the Creality one.
I've been looking for this for awhile and glad I got it. Good luck guys.
