I do my homework for month , look for a projector that I could use for my power point presentation at work so I would not have to keep borrowing from we it department . I do not want to have to spend $ $ 1,000 s on one either . some of the really good one can be quite costly . at the same time , I do not want one that could not provide a adequate , sharp picture . I also want it for home use to show movie at home or do movie-maker picture presentation for family gathering . not only be this projector price reasonably -lrb- I buy mine refurbish for under $ 300 ! -rrb- but it be so simple to operate and the picture be just great !!! I set it up on a table 6ft away from the wall and get sharp , clear resolution with a screen size of about 5x3 ft. . it be light and compact and I carry it around with ease compare with the cumbersome unit I use to have to check out . I only hope that I get lot of use from it before the lamp wear out . only time will tell . I hear that a lamp be costly to replace and that they only have a certain number of life hour before they burn out . so far , I be very happy with my projector . it have exceed my expectation and I highly recommend it .
