morgans dad, I have read your posts, and also the negative, as well. I hace the Digital Blue QX3. It is not quite as good as the "5", from the pictures I have seen posted. However, I have had good results, after modiying the plastic "barrier" so as to allow more light. I also made a base, contoured to allow it to seat in a ring, which in turn, mounts on mt QZs stereo-Zoom scope. The focus adjustment on the unit is so touchy, that it is frustrating to use. With the changes, it is quite managable now. I have a vision problem,and naturally, need something that will allow an image on a large screen. It was used on my 27" TV! It works dine, but I like a bit more control on the magnification, than is available, (10X, 60X, 200X. I like 20X, and 40X for most of my checking. It works better if you have a light source that is better that the integrated light. There are other "pro's, and Con's), but they are not needed here. For the money, it will do what you want, as evidenced by others who have made some p[rettynice photos in their posts. If you are satisfied with the rsults, after you have gotten familiar with it, then who else counts? We have our own likes, and dislikes. Enjoy, and it will be very easy for your son to use, as well.
