much better quality and feature set than I expect . absolutely no issue with its brightness when use in a dark room . I project to 42 '' . no issue with its dvd limited resolution . fantastic feature set ; very small -lrb- cigarette pack size -rrb- , lifetime mtbf , hdmus -lrb- with pcm audio transport -rrb- , VGA , build in speaker -lrb- albeit feeble -rrb- , stereo audio out -lrb- extract audio from hdmus -lrb- pcm only , I presume -rrb- , tripod mount . some neg be : its a noisy sucker in high brightness mode -lrb- quiet in medium brightness mode -lrb- just ok brightness -rrb- -rrb- , non-uniform focus , so lightweight that it be hard to make stable . I recommend mount it on a miniature tripod . I give the pk301 a happy thumb up . its not a flexible use device . it must be match to the right situation . I use it as a bedroom projector . I be look forward to future generation of pico projector because the pk301 prove to I that pico projection have a bright future .
