Automatic Fetch Machine

After surfing the net looking for nothing in particular, I discovered this nifty little gadget.  “Home Made Tennis Ball Gadget” which automatically launches tennis balls for your best friend (either human or dog) to fetch.  The dog in the video definitly looks as if she could use some exercise for sure, and it looks as if she loves the gadget.  I’m wondering how long it too her to learn how to put the ball where it needs to go.  I think this could definitely be marketed as a pet product.
