Not perfect, but close.

After using two IrisPen whose average yield and relatively short lifespan, I tilted the scanner mouse. A software bog after a few weeks, corrected by the aid of at IRIS, and go again. The idea is good, and multiple applications. We must heal his hand, do not scan in a vacuum, and ensure that the scanned sheet does not move and does not warp. Then you will have a remarkable and fast text recognition. For the image, too, is interesting, but it is very ugly if you try to enlarge the result, even choosing the maximum resolution. However, this will be sufficient in many cases, to insert a small piece of text or an image in an email.
So far, approximately 2 months of use, it is rather positive and the price / quality ratio seems correct. An effort could be made on the choice of cable, which is steep and sometimes disrupts the operation - for maneuver there! As a simple 2-button mouse and a scroll wheel, it works too.
