Gradually, I found out how to use the functions. I have not much used. In the standard configuration the scans are very pale and noise relatively strong. The sharpness is okay, but not good. The "Scan" (actually is well photographed) is quick, about two seconds per image plus about one second for Use Save. But since you always insert the negative only in the holder and then push by hand and each image must scan individually, which is in large quantities just for Patient.
The editing features offered by the device itself, sometimes very slowly (turn image takes three seconds). There is not at any point in a back button - to get from the scan mode in the USB mode, you have the device off and on again.
Overall, I am overly excited. The scanner comes back, I'll try a model from a higher price range.
