It is sort of crazy that it comes with a quick set up guide but no operating instructions. I'm used to looking things up though and easily found the PDF on the 3M Website.
It would get five stars except for a couple of negatives:
1) Operation was intermittent apparently due to a bad battery connection; however Amazon replaced the original unit within five days of being notified
2) while it supports jpegs apparently there are jpegs and then there are jpegs: my wife uses two cameras, a Nikon SLR and a Nikon pocket camera; images from the SLR transfer via computer to the device with no problem, but images from the pocket camera give a "format not supported" message. The workaround is simple, just run the image through any photoshop-like application to reformat it and it works fine but it is puzzling that the problem exists at all.
As stated in other reviews, this device is not really suitable for projecting presentations for groups, but I would highly recommend it for any more intimate setting such as display of photographs to a friend (setting it on a table and projecting onto a sheet of white cardboard works fine) and it is absolutely perfect for my wife's art application.
then doesn't support jack for formats, cant even get normal word files to work or pdf, even though it claims support for both... god forbid i get into the dance ive dealt with on file formats, even with i used the same codec used in their demo (by looking at the four-c code in the file), the video only plays sound... it seems that if a video is over 15 megs it wont work either, now try to find a h.264 under 15 megs ;) ). And that joke of a browser they have even in firmware 4.0 wasn't even worth the firmware space, it reminds me of the old Netscape project with an ancient windows ie feel... its not a bad little device for messing around at home, but i initially got it because of the six sense project trying to convert to android, which obviously wont be happening. oh and this thing is heavy and probably too big to be hanging around your neck all day for those that do go forward with the stock WuW stuff (or carrying around for those not playing with the project). I'm not sure what the designers where thinking when they made this but they added lots of stuff (and charged for it), but at the end of the day, all the extras they added they only HALF added so its basically back to being nothing but a video slave (that only supports vga or standard video out, no HDMI)... and its not that horribly bright either, i suggest you hold out for a different model, i think ill be donating this one to the kids to watch movies on (FROM THEIR PC ;) ) and try another for my project.
1) Image: It is very clear and defined when projecting from the SD card, with nice bright colors. However, a big dissapointment was that when connected to a laptop the projector is not compatible with resolutions above 1024x768 (although the documentation says differently). The image would display but it had multiple horizontal dark lines which made it unreadable.
2) File compatibility: When projecting from a laptop and using powerpoint (at the right resolution) the slideshows look the way they are supposed to. But if you move your presentation to the SD card, the projector uses an application to convert it to a format it can project and in the process formatting is altered (not only fonts, but also spacing, pictures, and colors) This detracts from the portability advertised as one of the strongest points of the device. I tried with old and new (Office 2007) PPT files (same thing happened). PDFs display well. Did not try pictures or spreadsheets. Projecting YouTube videos when connected to a laptop works well. If it had problems with a laptop, I am assuming it won't project from Bluray players or HDTVs with out ports.
3) Connectivity: Has a USB port to transfer files (expected), an audio port (I don't see the point of connecting your laptop (with better sound) to use the projector's tiny speakers. The only video port is a VGA port, which is the likely culprit for the lower resolution image. You would expect that in a time when most new laptops are built with HDMI out ports you would have that or at least a Super Video port. But maybe there are limitations stemming from the size of the device.
I don't have a comment on battery duration yet, but I noticed the projector got warm after a short period of operation. I would like to know if there is a way of changing the lamp when it dies...but I am guessing there is not. Pluses, are that it comes with a tripod and a little bag to carry.
Even with these flaws I think it manages to be an acceptable projector that does the job and is portable at the same time.
