Ive tried them all, from little plastic balls to foam ones. Nothing and I mean NOTHING works as well and as true to a real golf ball then this product. I have a small size yard and it was hard to try and practice with real golf balls (without giving my neighbors small heart attacks). So after trying and trying to find a good practice ball, one that was not a ping-pong ball (the plastic ones) or something that looked more like a cat toy (the foam ones). I found these little guys and willing to try anything at this point, I picked up a set. I was truly blown away. The feel, the sound and the fact that you can draw and fade these things had me convinced that this was a great product. Well after 3 years and buying over two hundred extra birdieball Im truly hooked on them, trust me youll love them!!!
