Great device - if one does not have much to scan!

+ Really small and can close: is then only 7x10x28 cm small (HxDxW)
+ Processed very valuable
++ Great software (see below):
...... Automatic alignment and rotation of the templates
...... Generate searchable PDF's
...... Various other programs
++ Good reliable feeder
++ Batch (about 20 leaves)
++ Both sides are scanned at once
++ Operation with power supply or via USB,
which is required for the latter two cables: doof! But I think that a USB cable you can tinker with an additional connector: then that's great of course: Place the device next to your Mac, connect a cable - ready!
- Scan Speed ​​something very "leisurely"
- But quite expensive (280, - EUR) - but it can also be much more than for example the even tinier "Doxie Go"

Overall impression:
- Super portable and small,
- Very valuable processed
- Good reliable feeder (stack)
- Slow (20 seconds per sheet)
- Expensive
- Only recommended if you only occasionally wants / needs to scan

I have bought he prefers the "ScanSnap 1500", although that is still expensive:
- Scan takes only 2 seconds per sheet (two!)
