Just watched it and nothing special nothing learnt in my eyes.
If you are just starting up then buy it and watch how wfp is done.
If you have a view problems then watch it you might find the answer on it.
If you are an experienced wfp, i would buy it too just to watch ProPole in action.
Be warned the sound quality is crap coming out of a surround sound system
The sound did not know which speaker to come out of, one minute the left front then the right back one. Bloody annoying
