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.

Great product
Size: 19inch
Excellent quality! Highly recommend. I love that you can wheel it around to other areas and the wheels lock in place.

Good umbrella stand
Size: 21inch
Works really well. I filled it with water and it works great. The wheels worked great on the pool deck. The umbrella stands upright even in the wind here in Florida. Worth the price. Multiple pole size inserts. 2 pole security screws.

As Advertised
Size: 19inch
The product seems well constructed and rolls easily when wheels are unlocked, even with full weight. Had windy conditions recently and the umbrella was held steady.
