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.

Surprising quality and ease
The quality and ease of using this product was surprising. I frequently scan newspaper articles, and they rarely fit on a flatbed scanner. Thus, I had to use Photoshop to stitch together 2-3 scans of the articles, which took considerable time. This scanner will handle A2 size paper, which is big enough to capture all major newspapers (e.g. Wall Street Journal), is easy and fast to use, and delivers crisp clear optics. It even has its own source of lighting. Excellent buy, and I rarely take the time time to rate products.

Quality of image
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

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.
