I purchase this projector in August of 2011 and enjoy use it to project on my ceiling at night , and when the power go out in all of southern californium last summer , I and my roommate be able to watch netflix on this baby . just recently in February or so it stop project all three color so the hue be a very red color and no adjustment would change it , and then it would power off after 45 seconds or so . I contact the company who get back to I within 24 hour and have I RMA the unit back to they . they let I email they my tracking number and immediately send out a brand new unit . they even let I keep all the accessory include the battery of the original unit . I get the new projector within 4 or 5 day of the initial rma request . this company really stand behind they product , and for that I be extremely impressed . the projector unit itself have a pretty decent picture for such a small device . my battery life be somewhere from 35-40 minute on the brightest setting , but i can easily plug it in while project to watch as long as i would like . the one caveat be that it must be almost completely dark in the room for a larger picture . but once it be dark , i can project a entire wall with the image with pretty dang fine clarity .
