One set of two stopped lighting after a couple days. But was able to somehow locate the breaks and repair the circuit. I expected something less fragile.Very pleased. Came out just before sunrise one morning to find these were still lit.These came in a two pack. I have 2 glass gazing balls so I put a strand in each one and they light up beautifully! Everyone thinks that they actually came mounted inside of the gazing ball. I'll never tell!I have these up in my back yard and they work great.Love itLove these lightsThis 2 packs of warm white solar light string is a good product. They are easy to charge and have a good user manual. They occupy an area of 78 feet and each has 240 LED lights. They are on a flexible copper wire and can be easily bent into any shape. I placed my mines along the edge of the top of the garden fence and placed them Wrapped on some parts, it looks great. The advantage of copper wire is that it will fade to invisible in the dark, and you only have the display light. There is no plug, only solar charging, and an on/off switch, which is a great supplement.When they are turned on, they will automatically enter when it is dark and turn off automatically when it is dawn. They have the added advantage of being waterproof, and the marked working time is 8 hours after being fully charged. They have 8 different flash modes, which are very suitable for different occasions, because the lights I prepare for the party are completely different from the lights I prepare for a quiet family dinner. There is also a memory function that can remember the last setting you selected, which means you don’t have to keep swiping options to remember your favorite mode. The solar panels are adjustable, which is very helpful, each individual light bulb provides full 360-degree lighting.Could be brighter
