This has been my favorite bed material from whambam thus far. I liked the pex but it just doesn’t hold up well at all. The PEI holds up well and can be used for many filament types. I’m transitioning my printers all to textured PEI from PEX. My new pex sheets didn’t last 2 weeks.. and I use glue and wait to cool to pop off. I have had no issues with the textured plates using TPU, PLA/PLA+, PETG, and PCTG, just adjust nozzle height accordingly and wait to cool before popping off and you’re good to go.
