Okay
I like that it fits my umbrella well, hinges open for easy application and removal, and that it has enough light for us to see our food at night. I do not like that half of the outer lights do not work part of the time until I take out the batteries and swap them around. Fine enough for the price, not worth the hassle of returning.

Easy to use.
Works well. Light is bright. Our new patio umbrella does not have e a center pole, so the lights get somewhat blocked. But still pretty useful.

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.
