Pros and cons

Pros

Two different coating surfaces give buyers a choice between smooth PEO and textured PEI.
The listed PEI filament range is broader than the stated PLA-only use of the PEO face.

Cons

The stated PEO surface is limited to PLA, so it is not the side to choose for the other listed filament types.

Customer feedback reports mixed experiences with adhesion and build quality. That variability matters because the listing presents the PEI texture as a higher-adhesion surface, but the reported mixed impressions do not establish how this particular plate will perform in a given printer or setup.
