Praised: sound quality and portability. Criticized: brightness.
Written by Augur from the 11 reviews analyzed
This compact video projector stands out for its high portability, making it easy to move from room to room or during travel. Users particularly appreciate the built-in sound quality, which is judged to be excellent, as well as the effectiveness of its image flattening function, which greatly simplifies the display setup.… However, the device proves to be less suitable for use in bright rooms, requiring darkness to fully enjoy a high-contrast image.
