beware that this be a Budget projector with lot of connectivity include hdmus and have ok speaker ! I buy it for my parent outside US and they need a big screen to watch movie . the reason for pick this model be 1 . cost -lrb- single most important factor ... compromise on the resolution -rrb- 2 . lead lamp 3 . Voltage regulation -lrb- 220-240v -rrb- . as compare to non led lamp , there be no issue of change the lamp for this model . the manufacturer state 20,000 hr of lamp life . test the follow input : VGA with laptop , a\/v with dvd player , hdmus with upconvert dvd as well as xbox 360 . pro : - Budget - lead lamp - build in speaker work through HDMI port and have decent sound - Power brick indicate 110 ~ 240v input con : - please bear in mind that the native resolution be 640X480 ... downgrade resolution from laptop , or any input device connect . if you be look for a higher quality image then this be not the product !! - require some dark room ... just depend on how the light source -lrb- background or external -rrb- be located and the intensity - Power brick look and feel a little cheap - all function work through the remote -lrb- if you loose the remote then you be doom ! therefore -2 star -rrb- - product quality -lrb- i.e. the construction material , plastic material etc -rrb- feel very cheap -lrb- you get what you pay for : -lrb- -rrb- - the cooling fan produce noise -lrb- same level of noise as some of the bright lamp projector -rrb- . do not expect this product to be quiet ! other thought : - purchase at $ 250 . we target be that this projector last for watch at least 100 movie -lrb- ~ $ 2.5 projector cost per movie -rrb- . already watch 10 movie so far and clock around 10 hr of Xbox gameplay . - if you can afford to spend a little bit more ... then try to go for at least 1024x768 NATIVE resolution in projector ! - I will not recommend any projector below 640x480 resolution even for those who have very stringent budget !
