What to know before buying

Listing details to confirm

Listing measurements give 1,800 lumen for brightness and 1800 ansi_lumens for maximum white brightness. The title specifies 1,800 ANSI lumens, but the supplied entries use different unit wording, so treat the ANSI figure as a listing claim. Dimensions also differ between 26.3L x 16.5W x 26.5H centimetres and 26.06 x 16.51 x 26.24 cm. The listed maximum screen size and throw distances are not guarantees of image quality or fit in every room. Customer feedback is mixed on image quality, brightness, autofocus, value and reliability.

Who is it for?

A good fit for

Home-cinema buyers seeking a listed 4K and Dolby Vision projector with built-in streaming.
People who value automatic focus and keystone correction for a flexible tabletop setup.

Less suited to

Shoppers who require customer feedback to be consistently positive on image quality, brightness or autofocus.
