Review on 20 LED Timer Fairy Lights With 3 Modes And Warm White Twinkle On Silver Wire - Battery Powered With 2XCR2032 For 4 Days (6 Hours Per Day) - Ideal For Party, Wedding, Christmas Table Decor by Chris Hall

Updated: It is clearly stated in the description that they will run about 4 days using the 6-hour setting. My mistake for not reading thoroughly! In that case, they work exactly as described so I am increasing my rating!Original: After using 4 different strings from two different boxes, I have learned that these will only light for about a 24-hour period. I used them on the timer, to come on around 5:00 PM. After the 3rd for 4th evening, they all quit working. Great idea and they looked great what short time they worked. If you are looking to decorate for just one event, they would be worth it. If you want something that will last, you should look elsewhere.
