Seems like a good product, could use a couple improvements...
Size: 19inch
Product seems fine so far, and the adjustable size for the pole is good. Areas for improvement are a larger fill valve so you could fill sand with something other than a teaspoon. Also would have been better if all four wheels had locks and not just two.

Holds 100 pounds of water
Size: 19inch
Some assembly required. Rolls easily in direction of wood grain on a deck. Very difficult to roll sideways across gaps in deck boards.

Great toy!
Color: Grass Green, Size: Medium
We have a boxer and pit mix and he destroys everything. This toy however lasted the longest. He played with this every day and he plays very rough. But after 3 months I finally threw it out. It was still in tact but it was about to start falling apart. I will definitely buy another one.

Great for aggressive chewers!
Color: Mixed, Size: Medium
My dachshund pit mix is VERY hard on toys. She is a very aggressive chewer. She loves this toy and so far hasn't destroyed it! I was concerned because the center is softer, but because of the shape she is unable to get a good grip on it to chew it to pieces. Very happy with it so far!
