Warms up very fast and a little too noisy fans.
carina ferrari
Hopefully, the true issue is just "user error" and it will be resolved when customer support is contacted.
Enough brightness a room with dim light, where note-taking can still be done.

Size Name: 500 Lumen
I ordered this product on the day of release (not from Amazon, wasn't released yet). I am seriously impressed by it and will post a video after I clean up my place. It will also be with a cell phone camera so if it's not good enough I won't bother to upload it.

Fan & Brightness

Ok first, right out the box it is very bright and vivid. The colors really pop and are saturated, but in a good way. 500 lumens doesn't seem like a lot compared to bulb projectors but this holds its own. I have about a 90" screen right now with my light on and even on Eco mode (lower in brightness to save power everything is easily viewable. I don't even use regular mode as it makes the fan louder. The fan is not that loud but can easily be heard if the room is perfectly quiet. It sounds like a desktop computer with no dedicated graphics card. On Eco mode you can barely hear it. On regular, it's audible but nothing that would bother you. I sleep right next to it and it doesn't bother me one bit if I fall asleep watching a movie. In other words, don't worry about it. Some projectors have a problem with warming up and causing the picture to become out of focus but I leave this on all day and never have to focus it.

A recommendation, tape a piece of cardboard (or something that doesn't look as cheap) to the ceiling in front of the light that shines on the wall you are pointing your projector at. It will make a huge difference in brightness and won't affect the lightning in your room one bit. You will be able to watch TV with the lights on while only the wall with the picture on it will be dimmer. It works great and I don't even notice light is being blocked.

Size Name: 500 Lumen Verified Purchase
Length: 3:00 Mins
--Start of update on 1/22/2013
For the past few months, i have noticed that the video randomly goes blank, it displays "searching..." and the video comes back again. At first i thought it was not the projector. Later, i contacted customer rep and they said it's a HDMI bug (i should use shorter cables). But, i see the problem continues with all types of HDMI and VGA cables with different sources (laptop & cable box).

I am waiting for customer service to respond.
--End of update on 1/22/2013

This projector is worth buying. I am difficult at liking anything but this is a good projector.

+ Fan noise does make noise. It is not much and you don't hear anything when playing a video.
+ Video clarity is good. I don't see distortion or fuzzy pixels at all.
- BIG issue : Using SD/USB disk option is good as no wires, but no audio outpput makes this meaningless (inbuilt speakers are meek)
- When watching cable, if channel's resolution has changed then it tries to re-detect. Sometimes, it never finds, screen remains blank.
solution is hit HDMI again on the remote.
- There needs to be an option to buy warranty to protect this investment
- My Laptop --> USB --> Projector option to display laptop video didn't work. Customer Service is not able to solve this problem.

Note: Attached youtube video is a bit misleading. Projected video does not have any fuzzy pixels.
It is damn clear picture. I think the low lighting makes my Sony camera to creates a bit of fuzziness.

Note: Light coming from the projector illuminates the entire room

Note: Best results are when room is dark. Video is watchable is semi-dark / afternoons with blinds closed too.

Size Name: 500 Lumen
::::.. I've been waiting for a decent led powered portable projector for a long long time. In the past the specs and performance of a led powered projectors were downright toyish. 30 - 50 lumens were way too dim, resolution was a new low, and the best connection you got was so 80's s-video. In the age of 1080p, over few thousand lumens, hdmi, HDTV, up conversion, and every other bragging gimmick the past "pico" led powered projectors ended up in gizmo crazys trophy stash, quickly forgotten, and I could see why...
::::.. Well this projector will change all that... There are other led powered projectors out there, some cost over $8000 that are focused on home theater, and there are comparable portable projectors like the LG HX350T (Only 300 lumen - 1024 x 768 not even a true 720p), The NEC NP-L50W which has the same specs as the Optima, but costs over $750 and gets complaints on focusing issues, there is the ViewSonic PLED-W200 which is only 200 lumens,. The only one comparable to this projector is the ViewSonic PLED-W500 which is little more expensive. There are handful of others that won't get your attention as the ones that I've mentioned.
Most of them have some onboard memory for storing images, music, office files, and videos, and some have usb connection. I won't get into that because these are just added bonuses in which there was a small budget in developing, so the performance is very low at best (even dedicated media players have playback issues). Same goes for internal speaker which is ridiculously low and cheap!
::::.. Let's talk about this projector. This unit comes with all the connecting cables, but not the HDMI cable. HDMI connection is full sized, so you don't need a adapter.
