Summary: The bad: The Scan button is too easy to hit and when I was trying to scan a page in a book, when I got close to the inside edge, I had to move my fingers to get the scanner close to the edge and twice, the mouse hit the book and scan key and quit the scan mode. The scan button should be on the top of mouse, out of the way.
Summary: I agree with others who have commented that the position of the scan button is not ideal however the scanned image is great - clear and readable.at least for my purposes. The only thing I really do not like is that I constantly am getting software updates and then a window advertising Twitter and three other apps - I think I finally got rid of it by changing my updates to manual rather than automatic.
Summary: This is a unique product. It functions as a mouse, but also as a portable scanner when used with a laptop.The image resolution is very good and it is easy to use. When scanning at the edge of an image, particularly the edges of a book or magazine, the scanned image tends to get partially rotated. When that happens, I have been unable to get it straightened again and have found the easiest solution is to end the scan and start over, again.
