I bought a net around 2 years ago and it has helped my swing a lot in the fall and early spring. When the courses around me aren't open yet, I pull out the net and start swinging. It's also great to use right before a round. A guy once told me that it is very important to hit a couple balls before each round. It gets the muscles loose and kind of reminds your muscles of what your going to be doing for the next couple of hours heh. The net has saved my swing through the winter and I plan of using it for a long time.
