Hi,

I used one of these for 2 lessons running and found it really helped with my swing and getting the proper feel for the correct position. After each use , I then went on the range and was hitting everything very well.
The only thing I would say is that it is something you need to use everytime you feel as though you have no idea how to swing and need a quick reminder.

Hopefully I am on about the right bit of gear, (it is like a circle you stand in.)

As I said it helped me , but may not help everyone.
