I haven't got that exact model, I have the PrimeFilm 1800u from Jessops click here& which seems to be the same thing with a different label. It works ok, but if you have loads of slides you'll get sick of only being able to scan one at a time. To be honest I haven't scanned at extremely high resolutions, I bought it so I can put my Nan's slides on CD so she can look at them on screen so I don't need the print quality.
I don't use the supplied software to alter settings much as I import it all in to Corel PhotoPaint so can't comment on that side.
What it does, it does ok - and is better than the flatbed scanner I originally bought for this job (even though it came with a slide adapter).
