My advice is that unless you like wasting money or enjoy frustration do not buy this product. I bought this and it wouldn't install. IRIS support suggested I set up a new user account to install it under. I did this but it didn't work, I was asked to download a new version, I did so. After one use it locked up. After a long wait (weeks) for return codes, I got a new unit. I used it and on the second page the pen jammed and the input was completely scrambled. Judging by the response from IRIS this is a known problem. Following the suggested solution I replaced the cartridge, and tried again, now the unit turns on and off but does not save the notes. At this point I have given up. I notice that IRIS now offer a 2 year guarantee. I think you will need it. Apart from the hardware problems the software is counter intuitive to use - uploading and recognizing text is a two stage process, the interface is ugly and difficult to decipher, icons and buttons hard to see. But the aesthetics are the least of the product problems. Basically it doesn't work.
