Adhesion is definitely less than from a standard textured plate, and I've found I need a brim to stop warping - but that could also be due to the model printed (similar to my bolt/ball carriers).
Not sure how applying glue would impact on the holographic effect.
The fact that it can only work on the face on the bed, kind of limits its usefulness. Add in that grease from fingers also removes the effect means that its probably little more than a novelty .
On the plus side, the finer textured plate (than the Bambu original) on the other side works great. At only a tenner its worth it overall
