We bought a sample pack of your flex head tees back at the Milwaukee Golf Show in March and have been using them all spring. My son being an up and coming junior golfer, they have been a great help to him ensuring the ball is teed to the correct height each time. And they have helping my driving also. I would highly recommened your product (and have) to others. That's why we had to order more, we don't know what we would do if we lost one!
