First I need to say the reason I bought this scanner was so that I can scan film shot on an odd format 35mm narrow frame camera so I just needed a scanner that could scan negatives that I could do my post work on later if I needed to. This scanner does that with the brutal honesty that I needed so that I can fix my errors in post and also learn from them. If you took a crappy picture with your camera this thing will render a crappy scan. If your scan is dark or light blame your camera work not the scanner. I ran a roll of mostly overexposed photos through this scanner and the correctly exposed photos looked great, the overexposed photos, not so much. A little post magic with Gimp (free photo processing software, very hands on) and I have a great set of pictures and know what I did wrong. I had a local one hour place process and scan this same roll for me, and all the photos they did looked great, thy admitted that they "enhanced" them. This scanner shows you what you actually shot so you can correct it next time.
So how easy is it to use? From the time I stuck my knife into the tape on the packing box to the time I scanned my first frame only reading the instructions to around page three was about 6 minuets. It took me about 20 min to scan an entire uncut roll of film and get it onto my computer. The unit shows a live view of what you are about to scan so it is easy to position your film, the carrier centers it top to bottom, you have to do left to right. I still have not read the instructions beyond page three, and with a little adjusting on some of my photos they look great, next time I will expose a little better and maybe get rid of a lot of post work, tat was an hour that taught me the value of a light meter.
Some things to note. What is not in the box. There is no SD card, and no TV connecting cable but for $109 who cares I have SD cards, and the built in screen is good enough for the scanning work. The unit is compact, it is smaller than 4 VHS tapes. The film holder does a nice job holding the film. I didn't use the slide holder so I don't know. Like it says, you do not need to hook this to a computer so if you have power you can scan any place you want to like on a table with room to put things and not at a computer desk with little or no room.
Overall unless it dies some time soon I'm really happy with it.
