 I think it's a huge learning curve. I think it's a huge mountain that you can't ever possibly get to the top of because it's like having nine scan tools. I'm better with some than I am with others because I use them more often. And then when I finally get around to using those ones that I don't use on a regular basis, but I've done my software updates, something changed in them. And I have to look in different places to find what I'm looking for.
