Well, I can't say I'm using it, not because it is not good but because I have not been doing any video editing for quite a long period of time.
I did have a question for the author at that point in time which is that I did not find any support for mov, the native format used in my Nikon Digital camera for which I wanted to do some editing.
So that was a hurdle for me then when I wanted to do some of that. And that was wow, maybe 3 years ago. Maybe things have changed for the better, then maybe not (change is not necessarily good).
So I would say, do check out what type of videos you need to edit and make sure it supports it - don't assume and of course, download a trial and see how intuitive it is for you.
If you are not sure of anything else, do email the author. If I remember correctly, he was quite responsive.
And if you do decide to buy, let us know the outcome of that decision.
