Not for super aggressive chewers even though..
My 10 month old Mastiff chewed this pretty well for a couple hours but I had to take it away from him as it has pieces missing and its not a complete ring anymore. Definitely not indestructible or even close to indestructible. I was sure hoping though. But nope.

Great Product
My Dog loves this thing, and he tears up everything he gets a hold of, all the time. This thing has been durable like no other toy we have bought for him. Great product, highly recommend, and I would definitely buy it again, but I don’t think I’ll have to because this thing is built to last.

Easy portability & Strong umbrella support
Size: 19inch
Its exactly as advertized! Pros: • rolls well • medium sized (not a tripping hazard & corner fit under the edge of all my furniture) • holds tall (through center of table) umbrella while open in minor wind with water-filled option. • multiple size umbrella pole insert included • Clear instructions. • easy to use brakes (on 2 wheels for security...4 wheels would be annoying to use every day) Cons: • will still roll with brakes on with a little force when I'm being lazy...it should not be this easy (I usually have a corner of the stand tucked under a piece of furniture anyways) • I would call this "light heavy duty" rather than "sturdy heavy duty" with water-filled option. I'd imagine sand + water as suggested would actually be heavy duty. • re-design suggestion: base of umbrella could extend down below the water tank for sturdier hold, but this is the best I've found.

Good buy
Size: 19inch
Filing it with sand (50 lbs) was a very slow process, but I got it done. The wheels are very convenient for moving the umbrella around, and the wheel locks seems to work well. So far I'm quite satisfied with the base.
