"Flexible Build Plate" is a pretty loose term in the industry. On an Ender, that usually means some kind of plasticy sheet with a weak magnetic attachment to the bed. These are the kinds that give flexi plates a bad name, and it's no wonder people who have them prefer to use glass.

Nope, its a coated sprung steel sheet with a damn good magnetic attachment on mine 
On another note, printer now checks bed level before every print
