After a few rounds of golf and getting used to how to position the tee in the ground, I have found that my shots are a bit straighter and have definitely noticed a good 10+ yards extra off the tee. So, so far, I'm pleased.
The only thing I do NOT like is when I tee the ball low to the ground on a Par 3, the tee gets bent and I have to "re-bend" it back to it's original shape.
