it be hard to believe that I can carry this little device around with I , which be the same size as a phone , only thicker , and spontaneously show my photo or a movie within 30 seconds . also , I be astounded by both the pricing and quality for such a deep discount off of the new price -lrb- buy it at Tiger Direct , as a refurb -rrb- . my refurb item be in brand new condition with all covering , bag and accessory that a new one would have . ca not believe all the cable that come with this to go along with all the datum port on this projector ! this be not mention in most review and I have wonder , prior to purchase , whether I would even have a iPhone cable , but it come with a Dexim connector which take the provide 2.5 mm to 3.5 mm phono plug . I can connect to my iPhone , iPad , laptop , desktop pc , and also use a internal micro sd card up to 16gb which will hold roughly a dozen full length mp4 movie . be sure to use the include converter software if you movie be larger than 720x400 . again , the condition of my refurb unit be pristine , just like buy a new one . Technically , the brightness for 20 lumen be much better than anticipate . of course , the farther you be from the surface you project on , the dimmer the image , but I be able to regularly project 50 inch diagonal image in a dark room which be fully saturate in color and with great contrast ! get a bit warm , but not hot . the provide padded zipper case allow you to safely carry in you pocket and have it with you all the time . instead of invest in a expensive screen , I buy a large , white , folding project board of foamcore material at a office supply store for around $ 15 . Works perfectly and fold up to put in you car or carry around . it be large -lrb- roughly 26x36 '' but very light -rrb- . off the cuff , you can use any light color surface , even window shades , wall , or blind in a pinch .
