Kit was supplied in a very small box (for the price I imagined an impressive package). The packaging is very well designed and the parts of the kit beautifully engineered. A long way from the standard Mk8's etc. Fitting the kit to a FF Creator pro was very straight forward with the necessary tools supplied. I found FF's instructions on the website and U tube video very helpful and clear. No instructions were contained in the kit. My fist prints with PLA were flawless out of the box but some fiddling with the tension screw setting have been necessary for ABS. I'm very impressed with this kit as an upgrade and expect it will provide good service once dialed in.
