I have pre-order this projector for almost a month before it be ship , which give I time to contemplate my purchase decision . I go around to the shop and check the pk 201 , 102 model and other brand like the 3M pico projector and the Samsung palm size lead projector . especially that I have a full size dlp hd projector that i bough last year . the inconvenience of have to setup the screen and the speaker in the garden to watch a nice cinematic experience on giant screen reduce these occasion to just a handful through a year . I have high hope for the portable battery operate projector but I be aware of the fact that its power be low and can only be use in dim room . it finally arrive , and much to my surprise it beat my expectation just out of the box . it look and feel better than any of the other one i have examine first hand . the casing be sturdy and compact although the zoom swivel look fragile . the picture quality be very good and can certainly beat the quality of a regular tv . i use it with a nokium micro sd card from my old mobile and i run a slide show on the ceiling with short video it take my breath away . i hook it up to my iphone and watch a full movie in my bedroom in full widescreen mode , you will be in for a good surprise : -rrb- you only need the av cable for the iphone or ipad and a bluetooth or wire earphone and you have you 100 % portable cinema box that fit in you pocket . I also try it with apple tv connect through the hdmus link . it deliver a very nice picture . the build in speaker be good enough for my kid to watch cartoon while sit just behind the projector . although I love this projector i have a few comment to make . the battery life be not enough for one full movie and do not charge well if you operate the projector while it be plug to power source . it heat up a little too quickly , i know it be summer time but in 10 minute it be case be hot . with that say , my final verdict be still excellent and highly recommend . I also recommend the follow accessory : 1 -rrb- a small tripod be very important for ventilation and also position 2 -rrb- the remote be very handy because the button on the projector be small and as they dim you can not make out which button you be press . also good for slide show and short video off the memory card .
