When you buy a microsoft product, you buy the right to use their product within certain constraints. You do not suddenly own the content. I would not call Lees website a subscription site, because you don't have any regularity to payments, but the same as buying licenses (a one off payment for a product). If you want to see a video, you buy a license for 4 views. You do not own the video, and you cannot view the video (use the product) without a license - the same as microsoft, but different rules for the license. Just my thoughts on why it is NOT a subscription site.
To bbirdman:
On the other hand, remember, his video is aimed at EVERYONE, he gives a very good reason for why he thinks body rotation is not THAT important (not sure if its this video or another of his). This instruction would be excellent for someone learning to hit their shots - lee is promoting simplicity, not TOO MUCH body rotation - which some would consider IS possible. Watch some professional mens singles and you MIGHT be surprised at how little body rotation they use - they do use SOME, but surprisingly little, I found. Also remember, that having body rotation without properly using your arm (and specifically getting your elbow positioning right at KEY moments), then there is no power at all because you have no swing technique.
At the same time as this, he proves with his demonstrations it DOES work, and the initial setting of the elbow leaves the chest open, which is the only real requirement (in my opinion) when setting up for a shot. If you combine THIS video, with his other smashing videos (which you might have to buy) and his videos on posture and hitting techniques, then ACTUALLY I think he has covered most of the important things, but in a very simple way. You must remember, this video is ONLY his opinion on how to use your elbow when you smash, and in general.
Finally, remember that this guy HAS coached professional players, including robert blair, and english doubles player. Robert Blair was an extremely powerful player compared to most - not as powerful as a Fu Haifeng, but more powerful than a Cai Yun. This is probably not a fluke on Lees part
Once again, I just wanted to help you consider a different perspective on what you have seen. Imagine a beginner and intermediate player - how beneficial it would be, for their development, to tell them to focus on their technique, not the body rotation aspect of their technique. It would do most of them wonders!
