Crealty 3D Printer Build Plate Adhesive Magnetic Bed Flexible PEI Sheet Surface 235 * 235mm for Ender 3/Ender 3 V2/Ender 3 Pro/Ender 5 Hot Bed Mat 3D Printer Platform

This is a genuine Creality Ender PEI coated spring steel bed, the performance is exactly the same as the one that comes with the Enser 3 S1 pro. Adhesion is reasonably good at heated temperature and prints self-release almost 99% if not completely as the temperature returns back to room temp. The caveat being in case of power failures, although the printer can resume, the cooling down causes the print to release making auto-resume useless. I'm back to using glue sticks for large or critical prints. The glue washes off easily if I want to use the PEI surface as-is too.
