this be a tough review because this be the first projector that I have purchase . I be really blow away by the absolutely beautiful , breath-taking image that cover my ENTIRE Green wall , but I end up have to return it for some of the follow reason . when it arrive , the seal look broken , the monitor cord be miss and a rbg to monitor cord be in its place . the native resolution be 800 x 600 , on my computer , xbox and cable output . THERE WAS no usb port ! which mean that you have to by the custom optimum toggle for $ 123 if you want wireless . and you will want wireless because , you have to set you projector in the center of the room , on a cart or heavy duty tripod . the sound be poor from the projector but I be able to plug in a speaker system into the headphone jack . too many wire come from my tv , wius , x-box , sound system , plug , cable , to the center of the living room with little kid run around for my comfort . if you do not mind use a cord , you can reduce it by purchase a multi-port hdmus switch for around $ 15 . the other problem that I have be the focus be really tight . there be no fine tuning and it be all manual . beware that 3d ready do not really mean that it be 3d ready . that mean you must have a computer with a strong enough graphic card that put out 120 hertz . x-box and blu-ray 3d be not currently compatible until a new $ 400 part come out that will have to be add on later this fall or sometime next year . then , plan to pay extra for the 3d glass , over $ 100 a pair , and possibly a special 1.3 to 1.4 hdmus conversion cord , depend on which website you review . the last problem be that this be not very portable , although it come with its own backpack , which be really hip for teen-gamer ! the projector itself be very flimsy make of cheap plastic , I would not trust it in the backpack from be crush or bang around , and I sure would not trust a teenager with it . the lens cap be useless . it do not twist on and will not stay on . I would be worry about it slip off and scratch the lens in a backpack or any type of travel . the size of the gt700 be quite large , it fit in the entire backpack , although it be light due to the cheap plastic wrapper . I give it a three , because of the outstanding image , which would be a five ! but the flimsy , dollar store plastic wrapper , and bulky size would make this very non-portable to business traveler . for the build , I give it a one . if you be live in a really large home , with a huge wall , and can mount this from a extended projector rod where ceiling fan , or light fixture will not get in the way , then this may be the right projector for you . this would make a good projector for a school or business if it sit on a portable cart , or on a board table . the light be quite bright and impressive in the daytime .
