Just bought a couple dozen of these and am truly amazed. I highly recommend these for back-yard practice, as an alternative to "wiffle balls" or even hitting real balls into a net. The great thing with these is they feel very much like hitting a real ball, and their flight is similar to a real ball as well but they travel only about 40-50 yards. You can actually, fade and draw them. It's really nice to be able to go to the local park and hit these around instead of having to go to the driving range. If you want to find out more go to birdieball.com

This is a great site! Thanks for all the tips!
