the 3M mp160 pocket projector be a perfect little device for the corporate world , and that be mostly likely what it be mean for and all it be good for . any videophile or audiophile will cringe at the measly 30 lumen of output and the flat sound speaker . then again you be not mean to watch movie on this thing . video : the video be a weak 30 lumen but for static graph and image it do the job . if you project on a wall expect a fade image since you need all the reflectivity you can get . on a pulldown screen the image be not bad . the closer the projector the better . you can pull it back to get up to a 80 inch image but the bigger you get the more saturation and color you lose . AUDIO : this be not mean for watch movie but you can always use the audio of the source product from where you be pull the video -lrb- computer , tv , etc -rrb- . CONNECTIVITY : you can connect this projector to pretty much anything -lrb- tv , computer , ipod , Phone , Camera , etc -rrb- . there be plenty of cable include , but you may have to fumble around to find the right one as the projector itself have one propriety input . so you have to have a adapt cable . luckily almost everything you need be include . the one draw back of this model ? you have to have a input source of video . this projector have no memory storage so you can not store video file or any file of any kind . so some sort of video device must accompany the projector at all time .
