Ball is great, squeaker not as much. I do recommend though.
Color: Blue
Ball is indestructible maybe but the squeaker is not. Lol. My Cane Corso is a huge chewer and she destroys every squeaker we've ever bought. This one too. But the ball is still in good shape so that's definitely a positive.

Truly Indestructible
Color: Blue, Color: Blue
This Is the first "indestructible" dog toy that really lives up to the claim. My dog is a power chewing destroyer of all things that squeak but after 1 month there's still not one piece of ball missing and it's still squeaking!! It is his prized possession. I've told all of my dog agility friends about it. Well worth the price.

Perfect for large breeds, long lasting.
Color: Blue
Great ball, stands up to large breed chewers. We have had it a month now, and it still looks like the day we purchased and still squeaks. Great for playing fetch.

Durable and fun!
Color: Orange
This ball is perfect! I have a two year old Rottweiler and she loves it! It’s hard, and durable, has a texture to it so she can do all the things. She hasn’t put it down!!

Awesome ball, squeaker didn't survive long :)
Color: Orange
I have an obsessed power chewer that loves balls.... durability is excellent!!!! Squeaker didn't last as long as I hoped but stayed inside the ball so overall safety works for me.
