The scan quality is average. No access to the darkroom, the blow if dust gets stuck you find on every slide, unless you have a can of compressed air to send a powerful jet of air.
Also the screen is vertical: suddenly we see nothing when we ask the unit on a table, you must manually look to see the pre-scan.
The slide scan takes a long time, to avoid if you want to scan large batches of slides.
I have not tested negative scanning photographs.
