Bests & Worsts Reviews from Amazon

I have bought three of these for my business, to scan documents from the road and send them in to clients. I only use black and white at 300dpi, which creates a very small file but a very clear image for documents. This scanner does the job well, and none of my three scanners has broken down yet, after 6 months of light use. There are several drawbacks: 1) Almost every page gets scanned in a little crooked. I'm thinking that there is a knack to getting it to go through perfectly straight but I haven't figured it out yet, one of my employees does pretty well though. Anyway, it is good enough, but still annoying 2) The whole process is tedious with multiple pages, hand-feeding one at a time, going through the program to tell it to scan each page. I shouldn't complain because this is a portable scanner, but one day maybe someone can make a portable scanner that can handle multiple pages by itself. 3) Occasionally it has trouble identifying that a piece of paper has been put into the scanner. The easiest solution for me has been to unplug the USB connection, plug it in again and try again. 4) You can only scan individual sheets, you can't scan out of books, newspapers, etc., like the HP Capshare 920. (The Capshare is unique in that it was made in the 1990's and is still better than anything on the market today. Unfortunately they stopped making it, you have to find it on Ebay.) Everything else is great, it gets its power from the USB connection and does its job. Update 2/24/2011: It has now been a year, and all three scanners are still running strong, no problems. Problem #3 that I mentioned above has ceased to be a problem, I think I was somehow putting the paper in wrong. You have to slide the paper in far enough to trip a tiny switch, and then allow the scanner to automatically pull the paper in about an inch before you start the scan.
