Who works with nomadic laptop, this mouse / scanner is absolutely the ultimate weapon. Scan becomes light, super simple, fast and the product range with the PC in his pocket: one can take it anywhere. I even find it easier to scan large volumes with this tool than using a traditional flatbed scanner because it does not bend the book or the original document. Certainly, for texts or top quality, better to go through a more efficient tool but the quality / speed / ease of use is unbeatable! Go for it.
