I'm full-time editor and I bought this item to try and save a little time. However, once I have set it up I have found that I hardly use it at all. I admit that the reason is that I have been so used to using a keyboard for the past 7-8 years. I would only recommend this item if you are just starting out editing. I liked the shuttle wheel, and it is easy to configure, but by the time I think about using it again, I have forgotten which buttons I programmed for which operation.
It is a robust piece of kit that does look rather cool next to your keyboard.
