Bests & Worsts Reviews from Amazon

Overall it's winner. Need a Dollar Store set of small, thin screw drivers or you'll never get the screws out. Took 10 mins to: 1) find where the Velcro opening was 2) Unscrew the TWO (2) screws to open the ball. 3) Unscrew the 1 (3rd screw) of batteries' compartment. 4) Push the square button BEFORE U tuck Velcro piece inside cover 5) Finally time to play HOWEVER, once it's done when you DO PUSH SQUARE ON-OFF switch & tuck Velcro cover together, IT WAS SO MUCH FUN! Don't know about long life of batteries- 3-AAA (Triple A), but we played w it for a good hour & our Aussie who's not very destructive, loved it. I'd say, if your dog is rough on toys & LIKES TO PULL TOYS APART, you either need to pay super close attention or maybe this isn't the toy for your dog. Our Aussie isn't too destructive w toys. He got a bit scared when it jumped around inside his mouth, but didn't stop him from dragging it by the tail & shaking the heck out of it. It was definitely worth the $13 we paid for a night of fun with our Aussie. Would buy this one again.
