Choose based on where the mechanism can live
A floor-rising case occupies low horizontal space and can sit behind or near a media console. A drop-down cassette consumes ceiling or high-wall space and needs secure mounting. The better option is often decided by architecture before optics enter the conversation.
UST-specific alignment pressure
With ultra-short throw, a small tilt or wave can show up as visible image distortion. For either retractable format, side tension and repeatable stopping position matter. A screen that deploys to a slightly different position each time can turn projector alignment into a recurring chore.

Floor-rising units need power near the case; drop-down units need power near the ceiling or wall cassette. Think ahead about access if a motor ever needs service. A visually clean installation should not make maintenance impossible.
Why the PET Crystal Classic points toward floor-rising
The product’s central proposition is no drilling into the viewing wall plus one-touch deployment. That is compelling when you cannot or do not want to mount a large cassette overhead. If your room already has a suitable ceiling recess, however, a drop-down solution can preserve the floor footprint.
