The product, electronically is not bad, pretty well done and convenient to use. BUT with the software provides is maddeningly slow (average for 2mn30 PREVIEW), if like me you have more than 400 slides to scan, a number of coffee liter lol you'll need. At worst dedicated unable to do anything else a station specifically to this task! One last point, the result of rather poor for scanning slides in dark atmosphere then projecting it make good. I think above all to software processing problem and I also search a substitute.
