Leadbetter obviously has the credentials but this DVD is really not worth the money. There are sections on the swing, the long and short game, putting etc but there is no real depth and each section lasts about 10 minutes. There some OK tips but nothing you won't have heard before. There are also sections for ladies, seniors, and juniors so if you are none of these then a large part of the DVD is useless. Even if you are, these lessons are 10 minutes each so not really very comprehensive. You would be better off buying a dedicated DVD lesson.
Overall it was disappointing and I know that I won't be watching it twice ! My advice is to buy something else but if you must have it you can have mine - mint condition, hardly used.
