On first glance it looks pretty simple and straight-forward, on second glance, especially for run and gun guerilla type film makers, this would be a totally useful and valuable tool. I like that it has multiple applications, is small, light easy to use, looks pretty easy to set up as well. Still need to test out my Cinetics wheels, but this is something I am considering testing out on a future dvd.
Thank you to Andrew for the tip!
