They are great if they get over 6 hours of sunlight. Eventually you have to replace the rechargeable batteries but usually once a year. I really like the stars. They add a nice celestial vibe to my Halloween decoratingThese are so bright and long lasting! I feel like they went all night but I couldn’t stay up to make sure lol… but they are beautiful! Everyone complainants me on them already!!prettyA bit dimI'm pleased with these lights. They are a very nice, pure purple color (and not just a dark pink).I installed four strands outside today. The solar charger charged the included rechargeable battery during the day and the lights have now been blinking for about 7 to 7 1/2 hours. They still look great- nice and bright (for such small lights).It's fun that they have so many blink pattern settings. I wasn't able to time them so that the more complex patterns flash in sync with each other but decided that's not necessary to enjoying the other several other blink patterns or their nice color.I also liked that there is a good couple of feet between the solar panel and the first bulb, and that each box of lights comes with one stake so you can lift the solar panel up off the ground if using the lights close to the ground, reducing the chance of the solar panel sitting in rain water.I am buying two more strands for a friend to enjoy.Would of been cool if the stars were blieI have many variety of solar lights, these (particularly the blue stars) are some of my favorites. I have at least five sets in or around my home/garden and have sent several sets to cousins and nieces simply because I want to share their beauty. They'll transform your space in to a magical and happy fairy dwelling in no time.I love these lights so much, but the last string I ordered, which finished covering my porch after our recent move, stopped working just a couple days after the 30-day return window closed. I'm disappointed.The first two strings continue to work great. I hope the company will see fit to swap out the failed set.
