I recently bought this little giant to compliment my collection of Portable media players. I now use it regularly at night to watch TV shows recorded via Archos on my ceiling at 40" -50" and it works really well with Archos products. I primarily use it with Archos 504 that has the direct video out form the player, however I have also used it with Archos 605 with travel adaptor and it does the job just fine. Below is a mini review for people who may consider buying. You can buy it directly from the manufacturer at aaxatech.com
Pros:
* Tiny projector
* 30,000 bulb life, will never need replacement.
* Has built in memory of 1 gb
* Micro sd card slot (read my sandisk 8gb card just fine, a very pleasant surprise, manual says can read up to 2 gb)
* Portable with battery, in my battery test it gave me 48 minutes with speaker, have not tried it with headphones, I am assuming it will add more time.
* Works really well through a/v in function, one can use any video source.
* Built in software is good, I observed no video stuttering while using the micro sd card as the source of video.
* Supported file formats include MP4, MP3, WMA, OGG, WAV, AVI, WMV, SMV, BMP, JPG, GIF, and TXT.
Cons:
* Of course with 12 lumens you have to be in a room fairly dark, it is pretty much useless in a bright room. Best use in my opinion is at night with very little light. So, this may not be a good choice for people considering it to run presentations in offices. However, at night I had no problem watching videos on this.
* Does not come with a tripod, I found it difficult to hold it; it would be nice to see an accessory that may offer tripod that one could use even on uneven spaces.
* Sound output is tiny and useless from built in speaker, you may have to use either head phones or have it attached to some kind of music system.
