THE GOOD:
Hepler focuses on the fundamentals, and tells you how the swing should feel. For example, when speaking of the swing plane, he doesn't tell you to think about the plane, but rather focus on your balance, because if your balance is good, the swing plane will sort itself out. Also, I liked how he said to initiate the downswing by "surfing" toward the target. I believe that things like that are more effective than thinking about mechanics.
THE BAD:
The structure of the instruction. Hepler spreads out instruction over the course of 60 days. He has each day (about an hour of instruction) divided into different segments, such as stretching and warm-up, routines, and mental techniques. The problem is that he gives little tidbits of good instruction interspersed between the different segments, so you have to watch the entire thing to learn maybe one or two good principles for the day. I don't have 60 hours to spend watching him, nor is it interesting enough to. I think he's trying to simply make a one-size-fits-all program, but we all have different strengths and different levels of ability, and so most of what he is saying, or the routines he does are redundant and a waste of time for me. I have watched only 1/2 or 2/3 of the series, because I get so bored watching all of his routines, and then I try to skip ahead and find the good instruction, but it is hard to find because it is in short segments piecemeal through the hour. I wish he would simply do a video where he lays out all of the good stuff and explains the golf swing and how it should feel. Of course if he did that the video might be 30-60 minutes, and he couldn't make a fortune selling a 60 day program. Which brings me to "the ugly."
THE UGLY:
Make no mistake about this program: it was developed with money-making as the main objective. Not that there is anything wrong with that, but I do think Hepler has lost sight of a few important things--such as offering simple instructional videos (instead of the super long routine videos--as mentioned above), and also the customer service. I actually signed up for what is now called the "Legacy Program", for around $160. I received offers trying to get me to try out there new program for free--one year for free, to be precise. All I had to do was give them my credit card info. I thought "why not", so I tried it. I actually like the old program much better because the instructional parts are easier to find in the videos. It's almost like they disguised the instructional parts in the new series in order to force you to watch the entire series. But anyways, I was surprised to receive a receipt in my email the other day saying I had been billed $200 for a recurring charge from Tathata Golf. I inquired with Tathata the day after receiving the bill, and was told I had to opt out within a year if I didn't want to get auto-renewed. I showed them the emails that I received before and after signing up for the new program, and the emails said nothing about opting out or auto-renew, only that I would receive one year for free. I pointed out that I contacted them the day after I received notice and asked them to provide a refund (it's not like I used it for a while and changed my mind), and they didn't care. They simply pointed out the terms and conditions, etc., and refused my refund. It kind of blows my mind they would treat a customer like that.
OVERALL:
I can't recommend this product. Before I purchased the program, I signed up for free emails with bits of instruction (not sure if they still do this.) I liked the short videos, so then I purchased the program. Turns out most of the good instruction was in the free emails. If Hepler ever makes pure instructional videos, it may be worth it. But until then, I wish I had my $360 dollars back.
