It works and does what it's supposed to do, the #2 lens never gives a sharp full frame image but it still gets it right center, the #1 lens. I didn't have one Problems with the focus seems that everything is clearly in a circle. However lens number one also falls out randomly like number two, the color settings are interesting, the light comes out pretty bright but not super bright, the elevation control is pretty tight but I think that's good. For the most part, try to stick to the slides.
