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.
