They are a bit cumbersome to install, getting tangled up. I ended up putting the open umbrella on the grass upside down to string the lights loosely. Did not use the zip ties so far. Maybe next summer. They lit up great
after 1 day charging in bright sun. My umbrella has velcro strips at the end of the spokes which helps. I am pleased with the decorative lights. They stay lit all night.
I was blown away with the quality! The lights provide a fanstastic warm and inviting light that is a perfect 'mood setter' for enjoying a nice evening outside. What I really like about this product is the longevity of the lights-life cycle;Unlike other similar products (such as fairy lights), this product provides several hours of light when properly charged (from sunlight). I can't say enough!
