Optoma EP7155 review


A great projector in a small package

Small and stylish ; Great picture quality

Quite noisy ; Limited zoom ; Confusing remote control

Considering the size and the price, this projector manages to cram in a lot of goodness

Optoma EP7155 DLP Projector


Combination of size, weight, image quality and price

If there was a way to improve the sound volume then that would be great, but for me, not if it makes the unit larger or heavier

Excellent image quality for such a small projector, even if the room isn't completely darkened. Easy to set up. Light and portable.

None so far

This projector is very compact, easy to use and the image quality is very good even in a well-lit room and the noise is minimal compared to other projectors I have used. It is very reasonably priced also.

None that I have discovered yet.
