its a awesome little device . its small , have a hdmus port right on it , and it host my western digital passport like a breeze , and play most media from my drive with no problem . also , its plenty bright for standard bedroom operation - even during the day with average window cover . at night its startlingly bright for its size . and it be sturdy - no move part besides the fan . it be take a tumble once or twice as someone would foolishly trip over a cord , and it suffer no loss of performance . con -lrb- worth mention , but not worth pass it up for -rrb- : the remote control - its a bit of a mess , intuitive-wise . get around its menu be a chore . the itir receive port be on the back of the projector , where I find myself not be positioned - far to often . some of the best place and way to position this projector leave the remote out of line-of-sight . and of course , you would better not lose the thing , because many of the projector function can only be access with the remote control . I velcroe mine to my projector in the hope that it would keep they together . so far , so good . the power adaptor - its huge . its nearly as big again as the projector itself . kinda sour the pleasure of have such a amazing compact projector when you realize you have to lug a big brick around too . and contrary to my original thought , the projector have no battery of its own , only ac power . all that say , its still the best , most versatile product of its kind and the best bank for one buck in this category . it always work .
