Easy to assemble. Lights are very bright. Very sturdy even with terrible storms it's still working and bright

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.

Sturdy & easy to move around
Its solid & sturdy. It does exactly what it’s supposed to. You have the option to fill it up with water or sand , I choose water. It holds the umbrella in place. The wheels and handle make it really easy to move around, which is a huge plus. It fits perfectly and feels very well made. Great addition for my pool area!
