A great product works really well and the ball seem to go further off my driver.
Downside - if the ground is hard (tee held more firmly) they seem to break off at ground level
quite easily.
I've been using these type of tees ever since they first came out. They were recommended by our professional as a great tee to get more distance. They certainly do and they last. Very seldom snap, I think over the years since I've been using them I've broken 4. Lost a few though! An excellent tee.
