I buy this projector to use on a recent business trip . Works as advertise . nice and portable ; love that it run off a battery . I do not have experience with other projector in this category , but I be very pleased with the brightness and clarity of the image . one bit of warning : the stand that come with it suck . the thread be defective -lrb- do not thread into the projector -rrb- , and the leg would not stay in position . luckily , I have another desktop camera stand that I be use with it . I would avoid the `` spider-leg '' type stand . overall , very pleased with the device .
