Can't believe we got this as an add on for such a great price. Our husky puppy has been slowly getting into finally playing fetch at the dogpark and with this, we can make him span the whole length and make him sleepy much faster. He loves this thing!! He doesn't understand not to try and chew the launcher when I pick up the ball but he has improved in fetch game immensely. He can tell where the ball will go and he is so fast that this saves my arm so much pain after a round of fetch with our wolf (husky/german shepherd mix). Such a great item. Would suggest probably a longer one as sometimes I suck with this thing, but so worth it. Can't believe I waited until he was 14 months old to get this. IF YOU ARE QUESTIONING IT, JUST BUY IT YOU WON'T BE SORRY.
