No NDA and that TW business was so long ago...you are close, since Dr G would not "dumb down" ONR, TW bought the concentrate in bulk and could mix it any way they wished to maximize profit. TW made an effort, sending reps into auto parts stores (O'Reillys, Autozone, etc) to demo the product. I think they knew they were in trouble when clerks questioned the product and called it "snake oil". There's still pushback on ONR, Optimum recently offered an 8 oz bottle with money back guarantee and I got to respond when customers wanted their money back. Some just didn't understand how to use it, but others had unreasonable expectations. OPT did find some new users, though...
