Official Creality CFS, Multicolor 3D Printer Filament System, Anti-Moisture Filament Storage, Supports 16 Color Printing for K2 Combo/K1 Series CFS Upgrade Kit/K1 MAX/K1 SE/K1C/Hi

Prints well, color is very close to what is pictured. No issues with adhesion as long as proper settings are used. Filament used on Creality K2Plus, did not need to dry, used in CFS with desiccant tray mod printed and full.

I haven't needed to use these yet however I have been using Creality RFID hyper PLA filament with my K2 Plus Combo with CFS and they work great. I expect these to do the same.

Why did you pick this product vs others?: easy to install. Good quality, more issues than without but worth it! Clogging: More issues with clogging than without and a bit more difficult to clear out

the Install for my k1se was pretty smooth and everything made sense. In terms of the CFS it does its job and it will auto feed well. Though it does seem like a few filaments have trouble and not because of the filament itself but certain spool brands just don’t fit in there well but other multifilament systems like this have the same issue so meh. Still great and works well with most of what i print with and keeps with other brands with similar multicolor filament systems

If you are simply updating a K2 to a CFS system, this will be a direct install solution. If you are attempting to upgrade your existing K1 and K1 Max to multicolor, understand that you are very much getting no support once you install the provided firmware. The firmware is borked and you won’t be able to run flow calibration. Creality doesn’t seem to actively support this, despite selling the upgrade kits.

Jammed because of user error, it works great when I'm not an idiot that day, I even did the heater mod where you 3d print the heater kit to take the guts out of the dual dryer/heater & jam it in the this CFS works pretty good

Hyper pla for creality. Quality prints

This first CFS from Creality doesn’t work all that well. I’ve done hundreds of prints without it and really haven’t got my money worth with the CFS. I feel ripped off for the price. It has made printing easier and different layers of color easier but only when it works. The bags to keep humidity down isn’t that good (humidity still over 30 in a dry room/environment). They really need a heater in the CFS to bring down the humidity. I’ve owned this CFS for two months now and it prints air between 1/8 to 7/8’s of prints and it can’t finish most if not all slots (a gamble) when I print with Hyper or Rapid filaments. When it does multi color it always misses the first several inches of color in-between color changes so you start seeing missing layers of printing in different sections (prints look goofy with multi color when stacked and looks stringy at transitions). That’s where I feel really ripped off without a solution. It doesn’t live up to its advertising yet. The transition clearly has the color change in the discard but misses the mark when starting the layer. It struggles with its own branded hyper pla/petg spinning also (use plastic spools unfortunately). I even printed supportive covers over spool but CFS can’t handle with or without. Really poorly designed CFS. I bypass the CFS so I could get more reliable fast prints without it. The stock filament sensor is too tight to allow filament through (had to remove the sensor part but kept the pfte tube connector). The stock sensor doesn’t allow filament through without a 45 degree cut and lots of pressure by a human (another reason the CFS fails). I’ll may seek a refund or replacement. If I ever will get a replacement or way recommended how to fix I’ll update my review. Back to old school reliable method of printing without CFS when needed.
