The tray is a bit awkward to setup and load but resolution is very good, in fact too good for most of my slides that I had to down-sample to get rid of the film grain. The biggest feature for me is being able to load up 50 slides and let it run for a while. I have a lot of slides to scan and automation was the biggest factor for me.
Simple fix for reported jam issues, works great with cardboard mounts and am very pleased with results but does not handle slides with bent or warped mounts. This copier is not the fastest but I can setup a batch of slides to copy and let run over night. Works well with Vuescan on my lowend HP laptop.
