Hi Sassan.
Just spotted your posting.
I bought one of these units a while ago!
Got fed up with the slow Nikon.
These are very fast, as it basically takes a 5mp image of whatever is in the holder.
Mine looks identical, but is a different make.
In theory it's a great idea, but in practice I've found I can only trust mine with monochrome, or colour negative film....... transparencies I tried were all very very contrasty (in fairness the Nikon also struggled with tranny film). I've tried all sorts to get around it, but have also since read of others having the same problems. Responds best if the image is left in place for min of around 10 seconds as you can see the filtration 'settling down'
For a budget 'instant' scanner for mainly monochrome and few colour negative films, I'd thoroughly recommend. Great fun, as they are so easy to use too.
I used mine not a few days ago with the F5 and a roll of FP4, to 'remind' myself of the good ol'days LOL
