I have 2 of them the driver and the 5 iron, I probably should have bought the wedge instead of the 5 iron, the 5 iron is almost imposible for me to hit well. However I do really like using the driver, and when I am hitting it well, I feel like I can hit anything, it really forces you to learn centrifugal force, you'll know if you flip it or use your right hand at all. Great for swingers, hitters should stay far away. I don't use it as much since I've been reading Brians information, but it did get me on the path to swinging correctly, but I think I got more out of this forum than I did the tempomaster, at least it explains mechanically what the tempomaster is teaching me physically.
