Excellent customer service
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.

Simple to use, works well for large documents
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.

Help with my VIISAN.
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.

Very Limited
After spending an entire afternoon with this document scanner (it's really a camera) I decided to return it. My goal was to scan my documents and photos. This product is so so on document scanning. It's terrible for photo scanning. The image quality was unacceptable and the software, while somewhat easy to use, is extremely limited. For the cost of this device, I expected a better quality product in both hardware and software. Steer clear of this one.
