Like I said previously I have been using it on and off lately but think will use it more often as part of my warm up routine before playing or hitting balls. My Swingspeed is 110 mph, but I have got the Speedstik up to 115 mph, but at the moment, its a fairly hard swing were my balance suffers but its getting better. So hopefully over the winter, I can get it to 120 mph.
