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. 30min stack is a blessing when there are power cuts.
Summary: The worst thing about this otherwise great gadget is the extremely noisy fan (I measured 45dB at 1m). On top of that I found that most video files I have played with very low volume. It turns out that fault is mainly in the videos having a low volume soundtrack, however it must be said that other video playing devices I have cope with that easily by simply increasing the volume further. With the P2 its volume at max but stil far too low.
Pros: Very bright image for a projector of this size High resolution 800x600 and very well focussed even at the edges VGA input (most other projectors seems to omit this)
Cons: Very noisy fan No lens shift or even digital keystone adjustment Media player has insufficient audio gain (many videos do not play loud enough)
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.
