Typhoon I do most of mine at home in the backyard. I'm happy to work on it at the range as well, where one should do that at a golf course.
Never on the 1st tee box.
That said, I did catch up and join a couple of friends on hole 3, and played 4-9 with them. Seeing how there was a full hole space, I introduced one of them to those aero swing pieces. I had her take about 5 swings with one, then another 5 with both. After that had her hit her tee shot once the hole cleared, and she said that was one of her longest drives. I think she might be interested in her own set to try at home.
I figure that will be my acid test to see if these things really work as advertised. She is also about 20 years older than I am, and currently isn't hitting her driver 170 yards most of the time. It might be nice for her to get to 200, or close to it.
