1x2 Little Chipper Golf Hitting Practice Mat with 12 Backyard Limited Flight Practice Balls. Great for Hitting in Your Backyard. Durable Plastic Practice Balls that Hook and Slice Like a Real Ball BirdieBalls were introduced new product section at the International PGA Merchandise Show and WON "BEST NEW PRODUCT". You actually can feel the Birdieball at impact it feels like a real ball  but it only goes 40 yards. Now you can practice all of your golf shots in your own backyard or at the park. I even keep a sleeve in my golf bag and hit 3 extra shots whenever it gets backed up on the course (of course I had to give my playing partners each a sleeve because they complained that I had an unfair advantage). BirdieBalls are a great golf training and golf teaching aid for golfers of all skill levels You will love them because now you too can work with all of your clubs in your own backyard without a net.
