I have put only three stars this scanner because it must be admitted that it is quite slow. But probably not slower than others of his generation. Its use is so convenient that it can sometimes be confusing. Indeed, it is not connected to the mains but directly to the computer via USB. Once the software was installed (which, for me, need to go on the Canon site because I do not have a CD drive), the computer recognizes the scanner immediately. So just open the menu and proceed with the scan. I only scans documents and some photos from time to time. So I can talk about his own photographic use. But for documents, it is perfect. It takes very little space, and thanks to its mounting kit, it can hang on the wall (not tested). I recommend this purchase altogether.
