Expectations exceeded (and illuminated!)
I am so stoked about this purchase. Our outdoor lighting situation was terrible- motion-activated lights that cut out after ten minutes and zero power outlets outside. This umbrella light exceeded every expectation. Three brightness modes, all bright enough to actually see what you’re doing — no more squinting while socializing, reading, or attempting to do “work” outside. Cordless, easy to install, and long lasting. If you consistently forget to turn them off when you're done, you'll get about a week and a half from the batteries on the lowest setting.

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.
