this work well , but I do not expect it to have a decent lifespan at all . it seriously feel like a toddler toy . I have be play with it for several day now , and the image be very hit or miss . I can not imagine try to play any sort of game on this as the resolution and lighting be both sub-par . set the unit on my floor , point at the ceiling , I get a ~ 40 '' screen , and can clearly see the individual pixel . when watch movie , it be difficult , at best , to read any sort of text that may pop up . try to figure out the menu on my PS3 take several try to get Netflix to load . the internal speaker be actually one of the best feature about this unit . it provide ample sound , and have a wide range . it be prime operate area be in the vocal range , but gunfire and siren sound equally decent from it . so , so far I have list mostly negative , but for the right people , this may be the perfect solution . as a on-the-go unit , this thing be large , but could be great . use it with a mp3 player to watch movie make this incredibly versatile . if you want to put up a theater in the back yard , I imagine this would do ok -lrb- provide not too much outside lighting -rrb- . if you be not sure about get a full projection home theater , this be a good way to test the water to see if you want to invest in something more substantial and all the other goody to get with . if I would have have this on my Pete 379 when I be drive , this would have make movie watch a bit more entertaining . the 120 '' screen size on the side or back of a trailer would have be brilliant . so , I keep ask myself if this be a decent buy or not , and I gotta say that it be well worth the cost . I do wish I have continue look for a unit that include usb , VGA , HDMI , or other means of input , but I can handle use the standard a\/v rca plug for now . consider the cost of go to a theater , this cost less than a half dozen ticket . so , if it last more than 6 movie , it be a great buy . I be already near that mark , and it have not show any sign of meltdown ... yet .
