I have the Mini diascop ordered, since we have to sift through a wide range of slides to digitize and do not want to build the slide every time. For this, the device serves its purpose well. Simply tuck the slides and you will be displayed with backlighting. Even for people with strong lenses everything is clearly visible. The price is a bit high, it pays well only when we want / need to look through boxes of slides.
A slide projector does not replace the device, of course ....
