We both found good advice in the first video, the one that sends a video to you that explains your Death Move and then some techniques for working to improve it.
My husband found out his was freezing (locking his stance) over the ball, his fix was to waggle a bit before hitting to loosen up. Mine was casting, a narrow backswing and wide swing, my fix was to transfer weight and shift a bit more in a specific way.
The main video and subsequent videos were only available for a short time. After getting our fix, the video continued to drone on and one without seeing anything for quite some time.
Some people might not like the downside to getting the tip--you get signed up for emails about training.
The Revolution Golf website looks good, with more advice and videos. My feeling is its better to try to improve your game than not, what do you have to lose?
Another great video to see is Phil Mickelson's Secrets of the Short Game, read the benefits.
