This is a new hitting tee which is flexible enough to allow a real hit of the ball without damaging the racket, and without causing any impact injury to a child's arm or shoulder.
The ball is supported by a soft, protective collar, which cushions impact. But it's the flexibility we've been able to get at the base, so the tee pivots as the the ball is hit, which allows a proper follow-through.
A weighted base holds the tee in place - again facilitating a solid strike.
Adjustable height, too - you can vary it by up to 20 cms.
