Summary: At the recommendation of some positive reviews, I purchased 3 Strobe XP 450's about 3 years ago. I can tell you that I have had SO many problems - the main one being that, with all of the scanners, there is at least a 50/50 chance that after scanning one file, you need to restart your computer in order to start another one, as a message consistently comes up - "This scanner is being used by another application". I am ready to buy three different scanners and trash these.
Summary: I love this scanner...it is fast, generally bullet proof. There are a few weird things about it, like it doens't like to be plugged into UPS. It prefers to be plugged into a stip of the wall. It does lose connection occasionally (not often). The fix is to power off the scanner and turn it back on with the switch onthe back. It takes 10 seconds...MAX.
Summary: I have used PaperPort/Visioneer scanners for close to a decade, and loved them all. For some reason, though, their code gets worse and worse and their "support" simply does not exist. For some reason, in order to install a new scanner, you have to remove all vestiges (even hidden ones) of the prior scanner software and drivers. Forget installing TWO scanners (I have both a Visioneer flatbed and a Strobe XP 450).
