my office have be experiment with a few different minus projector . this MicroVision model be the one we be stick with for now . -lrb- we have 4 of they -rrb- it be a simple plug and play procedure . the picture be decent . the cable adapter be custom make for apple product . my only problem with this feature be that the cable be very short and there be no option for a longer line . this just mean that you need to be close to the projector if you want to control the program manually . the device be light and about the size of a iphone . i can absolutely tell you that when fully charge at its brightest setting and run off the battery . . you will get no more than 2 hour and 40 minute of battery life . it be a good product for now . . i say for now because we have already see a smaller device that slide onto apple device and it have the same luminosity . we will be switch to that brand as it come to market , but for now this laser pocket projector be state of the art for the consumer market .
