This projector exists for one situation and owners describe it precisely: a room where the projector cannot get far enough back. A 120-inch image from about six feet is the number that comes up repeatedly, and owners with a soffit, a ceiling fan or a shallow room treat that as the whole reason to buy it.
The comparison owners make most often is against an ultra-short-throw laser TV, and they come down on the side of this projector on cost: a UST plus the matched ambient-light-rejecting screen it needs runs to roughly double for a similar picture. The compromise they accept is precision. There is no lens shift, only about an inch of fixed vertical offset, and owners warn plainly that you cannot move the image at all once the projector is up.
The second precision point is about lag. Owners report that the lowest input-lag figures require no digital correction in the signal path, which means squaring the projector to the screen physically rather than keystoning it into position. Owners planning a permanent install are told to run conduit and decide the mounting point before the drywall goes up.
