Coming from the world of FDM printing with flexible magnetic build plates, this was a no brainer. I have an S4 Ultra, so there is a *little* bit more work with running the provided gcode to adjust the z offsets which needs to be rerun after any firmware autoupdates, but I can print flat things right on the plate and everything either pops right off, or can be easily slid off. No putty knife needed. The instructions that came with the plate were clear, and the companion page on Cults has all the details S4 Ultra owners need.
