The umbrella comes pretty much pre-assembled. All you have to do is join the bottom pole to the rest of the umbrella and you're set. It has a small solar panel on the very top of the pole to keep the lights going, so no batteries are required. The lights inside the umbrella are not bright, as they are supposed to be more for the "mood" than the light.
The solar panel on top works amazing as the LED lights are nice a bright and create a beautiful atmosphere at light up the area so well. I may buy 2 more for the other side of the pool. The fabric is very thick and sturdy and they were simple to assemble.
It works as advertised. it does light up nicely! Enough to have a conversation on a cool night.
Good quality, good lighting.Perfect.
Convenient with the LED lights and simple on off switch. I also used blue tooth color changing bulbs for my other outside lights.
