Great Projector

Ignore the 3 stars the other customer gave it simply because the screen size wasn't compatible with their viewing space Can’t believe how good this projector is for the money. Just have it displayed on to a white painted wall at the moment and the quality of picture is superb. Like with most projectors, I’d recommend not relying on the units speakers.

Good but not very flexible

Lovely picture, replacing my old Epson projector. But placing it in the same ceiling mounted location meant the picture was too big for my 100" screen and couldn't be reduced further. So had to swap it for another Epson model which is more flexible.
