Summary: I'm not a specialist in picoprojector. By comparing the product price and image gets it, is very good. Recommend its use at low luminosity. The colors and images are bright and clear. It is ideal for Power Point presentations in small rooms. Audio limited, but you can use additional horns.
Summary: For the size and price this projector is a great projector. Even though it only has 33 lumens it's passable in terms of brightness. Better with a projection screen but for the portability it's much better than most of the pico projectors I have seen.
Pros: Waaaaay brighter than my Optoma PK101. Waaaaay higher resolution than my Optoma also. Connects to laptop and displays good images. I can get 80"+ images in the dark! Best of all compact and portable - fits well in my laptop bag. Also has remote control which is a nice feature.
Cons: Battery life is short only 1 hour. Fan is super loud. Not bright enough for big meetings.
