I have tried each and everyone of them and they worked perfectly.Their Lenses have insignificant scratch (es) that doesn't affect the Image at all. While focusing the image on the screen when you are on the internet having a white screen, you might see a small insignificant hairline moving or you won't see anything at all. After you focus and the Projector is fully Lit, it will disappear.I am selling them at this price because of what I have mentioned and that doesn't affect the image at all.The Hours used on these Projectors vary from 3145 to 3272 Hours .You will receive the Projector , the Remote Control, the Power Cord, the HDMI Cord and the VGA Cord.I will not ship to Hawaii, Alaska, Guam,Puerto Rico and the P.oBox addresses.
