this projector be great for portability . it be small -- surprisingly small ! if you need something small , portable , and with a decent resolution picture , this be a projector to get . however , you need to know the pro and con with this one if you be look for the all purpose projector . pro : - decent resolution , even with the odd 858x600 . - small . I mean this thing be tiny ! - handle video well . - great menu option . Acer do a great job with they uus . - bulb will hypothetically last for 30,000 hour . now that be awesome . con : - it be not very bright , even only 9-feet from my wall . do not let the 200 lumen fool you . even in a dark room it be not sufficiently bright . for I this be a deal breaker . - fan can be a bit noisy , but not nosier than a laptop fan on high . this do not bother we in the least . but if you be sensitive to fan noise , then you may not like this projector . - resolution be not my favorite . even though I know this go in , after see the actual picture I be not impressed . overall : although this projector be not a bad buy , especially for its great portability , if you be look for a bright picture that do not need to be project in a very dark room and can even be enjoy in dim light or with ambient sunlight , I would look elsewhere . this projector need a very dark room to be remotely enjoyable . and any light will begin to wash out the picture , and I mean any ! after purchase this projector , and after try the Optomo pt105 -lrb- which I very much do not recommend -rrb- , I purchase the Acer x1261p . so far this projector meet all my need : sharp picture -lrb- 1024x768 resolution -rrb- , bright image -lrb- 2700 lumen -rrb- , portability -lrb- even come with a carry case -rrb- , can project a image at 120hz , and be only $ 50 more than this projector . the two caveat to the x1261p be that the bulb will only last around 6,000 hour on eco mode -lrb- which be good overall for a standard bulb projector but not compare to the k11 's 30,000 hour -rrb- and it do not have a hdmus input -lrb- although I buy a inexpensive hdmus to VGA converter here on Amazon to address this issue -rrb- . so for I , this be a better alternative to the k11 . nevertheless , if my con be not a issue , then you maybe happy with the k11 .
