First ball was great!
Color: Black Green, Size: 8 Inch
This ball was great! My dog loves it. I ordered another smaller one. It had no pump and the inside was separated from the outside piece so it couldn’t be pumped up.

Fun and durable
Color: Flag, Size: 6 Inch, Color: Flag, Size: 6 Inch
I have a 5 month old teething Whippet puppy and this toy is a favorite. She loves carrying it around by the straps, playing tug, and trying to chew it. I think it’s pretty tough and durable for someone her size. I could see how a shepherd might destroy it quickly, though.
I was surprised to find you have to inflate it, but the pump and needles are included and it hasn’t lost any air over several days of rough play. (I kick it and toss it to her. We tug with the straps. She carries it everywhere.) The material feels like a heavy duty soccer ball, just smaller. It’s the perfect size for her.
I’d definitely buy it again.

It's a (smaller) soccer ball with nylon straps. Will no last long for aggressive chewers.
Color: Black Green, Size: 8 Inch
As the item title states, it's a soccer ball with straps. It feels like a soccer ball, but smaller and doesn't make any noises. The 8 inch size just right for my 50 lb dog. He can't get his mouth around the ball, but can bite down on the straps as we kick it around. He also plays and tosses it around by himself. It's also easy to clean.
It's a good item, but suffers from two issues.
01) The nylon straps are tough, but not as durable as I though. My dog is aggressive chewer and has managed to chew them up a bit.
02) There is a nylon strap that is longer than all the others, so he tends to focus on that one. After about 15 days of playing with hit, he's managed to chew that strap up to the point that it's almost falling off. It would be nice if all the straps were the same, larger, size.

Highly recommend
Color: Black Green, Size: 8 Inch
I was skeptical that it would hold up to our aggressive chewer puppy (staffyX) - especially during teething. But it has survived past teething into adult chompers and is still fantastic! Its his favorite outside toy, especially the tags make it fun (and those have been holding up well too). If/when it fails, I'll buy another one.

great design, poor overall quality
Color: Black Green, Size: 8 Inch
My dog loves these balls. The "tags" are a great design. The problem I have is the quality as they aren't tough enough. He goes through them pretty quickly tearing off the tags and puncturing the ball. He doesn't get that these actually cost money!
Each one also comes with a small pump, which I guess is great for a one time buy?, but man, if you don't own a pump just buy one and keep one. I have no use for several of these cheap pumps. How about offering the pump as an add-on for a dollar or two?
