I have VF. I tried it for the first couple days I had it, then put it down, and have yet to return. I don't know where the issue lies, but it just does not feel intuitive enough for me, and the results I've been able to achieve are poor at best.

I've been working on a few other things lately, so I haven't had the time to return to it, but I have been thinking about giving it another try soon. If I can't achieve the sort of results I'm looking for, that will be the last time I try it.
