The included micro SD card has some documentation, some windows software and the obligatory example file gcode for printing. Loading up the sample creality PLA and setting it off it produced a very nice bunny model albeit with a noticable Z seam on the reverse side. Print quality was amazing though apart from that and it felt like a very good start.
I haven't used the Cura profile provided for slicing as I am a fan of PrusaSlicer now and I was pleased to see that there is a beta configuration for the Ender 2 Pro included in the latest version. I tinkered with a few prints using the default settings of the PrusaSlicer ender 2 pro profile and initially had reasonable result but with constant blobbing/zits at new layer start points. The ender 2 pro is a bowden set up and it's quite a short bowden tube which means that there is quite a lot of pressure in the hot end. I knew I needed to up the retraction amount and speed but initially this seemed to make little difference. I was puzzled but began to suspect that the included SD card wasn't particularly quick and that the machine seemed to be making some longer pauses at layer change than I expected. I grabbed a better brand micro SD and tried again, this, combined with what seem astronomically high retraction distances (6-8mm) and near light speed retraction rates.. (200mm/s plus!) the blobbing and oozing was cured. So far it's had trials with a variety of PLA and some nice Prusament PETG as well as some cheap generic PETG. It's handled it all very well.
So there we go. It's an excellent printer. It's definitely going to get used and it's probably going to get abused with weird filaments and experiments as, at the price point, it's a great printer to not be too precious about.
