What we liked
- + Smooth PEI style surface gives clean, flat print bottoms
- + 235x235mm fits Ender 3 and similar ELEGOO bed sizes
- + Heated bed friendly PEI holds adhesion across common filaments
Trade-offs
- - Smooth PEI can bond too strongly with PETG, risking surface damage
- - Single sided sheet offers no backup surface when worn
