Summary: I've been using this in my small business for several years. It has a lot quirks (I've lived with them) and if I need to scan multiple pages fast or need really good quality I resort to my wonderful ScanSnap, duplex scanner. Paper jams, loud squeaks come and go off and on. There is sometimes a software issue in that it sometimes conflicts with the printer/scanner that is also attached to the same pc.
Summary: First thing- If you are using XP, you might as well just throw out the driver disc that comes with it. I loaded it per the instructions and it wouldn't work. Following the trouble shooting guide, I totally uninstalled it, downloaded the updated driver from the website and reinstalled. It worked perfectly fine after that. Another thing you should be aware of is that you have to plug it directly into the computer. You can't use a USB hub, even a powered one.
Summary: I use my scanner to store old documents in my computer so I can get rid of bulky paper files. I keep the paper copies until I probably won't need them again; for example, I keep tax returns for 6 years, then scan them and shred the paper copies. I protect my electronic files with multiple backups including an external hard drive and flash cards.
Summary: I was very excited about this product, since it seems from all reviews even on website that what is scanned, even photos, come out as a scanned product should. First, be careful from who you buy, Amazon has a default of Datavision and they are making may pay shipping charges to exchange a DEFECTIVE product. So I wouldn't buy from them, this type of policy is just cheap and means you don't back your products.
Summary: I have purchased a total of nine of these keyboard scanners and have had to return (exchange) three of them. All three problems were related to the sheet feed mechanism. Quality Assurance seems to be lacking at KeyScan. Otherwise, once the scanner actually is working, it works very well. My users for whom I have installed this scanner all use the scan-to-pdf-then-email function and are very happy with the ease of use.
