Kestrell

I have a friend who is investigating the possibility of trying it, but I can't say how long it takes to train the software: an hour? hours? days? I have heard that this process is much easier in recent years, and I am wondering how easy is it for someone who is not a tech-saavy geek type.

Does anyone have any experience to share? Also, the person is sighted, so there's no need to worry about having to use it with Jaws.
