VIISAN S21 Large Format Book Scanner, Capture Size A2, 26MP High Resolution

We had a missing part that, after contacting the seller they acted very swiftly to replace this. Then followed up to ensure it had arrived safely. The product is excellent and just as described. Would thoroughly recommend.

The image taken from this scanner is not as sharp as I thought. I have send a message a few weeks ago but no reply. Geoff G & L Services Ltd

I ordered VIISAN scsnnerfor multiple document processing. I had a difficult tine getting it to work, so contacted tech support. After taking me through all troubleshooting steps, it was determined the device had an issue. The support team arranged for replacement of device and the new device works without any issues. I'm still learning about device, but very happy with it. Thank you to support team. Very professional.

We have been using two of these overhead cameras (they are not really scanners) to photograph fragile historic newspapers. With the newspaper open on a flat surface, one camera photographs the left and the other photographs the right, each one being controlled by an inexpensive laptop. The resolution isn’t great, so during post processing we have to bump up the resolution using imagemagick. We also use supplemental lighting and turn off the built-in light. My only complaint about the cameras is the hinge doesn’t reliably open to or stay at 90 degrees. Even with these issues, the Viisan cameras offer great value for the money. They produce a better and more economical result than using DSLR cameras.

Most of these Book Scanners love to boast about how fast their scanner can scan a book, but it is not how fast the scanner can scan, it is the editing in the app that takes most of the time. Scanning a page per second means nothing if it takes 15 to 20 seconds to edit each page. Most images come out skewed and need to be edited in the app, which is time consuming when you have 200-400 page books to scan and convert to PDF format. It have taken me over 1 hour to scan and complete a 300 page book The app also constantly freeze and shut down when using curve editing instead of straight line editing, which takes more time. And when you go to export the scan into a book, some of the pages turn diagonally. Scan quality come out good once edited, occasionally an scan will be blurred. Overall I give it a 3 Stars. it gets the job done, but it is not great as others.

I love it. I am computer illiterate. I can barely use email. It was very simple for to get up and working, Just need to work on understanding all the cool features.
