I used this item, it's good, but if you are a hard hitter, you will have to concrete it in. Broke mine within 20 mins, knocked it out the groung twice and broke the plastic seal so now it just spins round every time I hit the ball, but it can be fixed simply with a locking nut. Sounds good when you hit the ball, just like teeing off. Great item for all this bad weather if you want to keep up ya swing.
