I just wish it said how the timer works on the box...I read comments to figure it out.Good set of lights.Easy to use, they only require 3 AA batteries and automatically go off after so many hours with 8 different settings!Great Value. No complaints. Perfect for fall.When I initially opened the lights I wasn’t happy. There was a single button to cycle through light operation options. There was no setting for a timer and the timer feature wasn’t mentioned in the instructions. The only reference to a timer was a small clock icon on the box.I put the lights on an outdoor tree with all 5 strands in the on position. 6 hours later they turned off. GREAT, but I have to turn each strand on tomorrow when I desire lighting? Low and behold the next evening, the lights turned back on for another 6 hours!THIS IS A GREAT PRODUCT THAT HAS BAD DOCUMENTATION. If you want Christmas lighting outside and you don’t want to run power these are great!Easy to useThe lights are bright enough and I love the ability to change the light sequence- solid, twinkle, chasing, etc. I've had them for a few weeks now&haven't had to change batteries. The only down side is I don't understand the timer. They come on at the right time though.I liked these lights when they worked. Timer was pretty simple to set up and overall the lights were exactly what I was looking for. However they broke in under 6 months. I purchased in December 2021 and these broke early March 2022.
