I bought these string lights in January 2021. They were plugged in and lit 24/7, no breaks, until the day they died in May 2024, and I am pretty sure that I was the one who broke the plug connection by smashing it with something heavy rather than the product failing. They outlasted about 6 other sets of string lights getting a lot less use (3-7 hours daily rather than 24). Yes, they're SMALL lights and the wire connecting them is thin and easily tangled, and they're simple with no fancy controls or apps. But they have a nice, warm and cozy light and the thin wire means that they make lovely natural garland shapes if you hang them in sections. I get compliments on them all the time. And they are very durable and reliable, I certainly wasn't taking good care of them and never broke them like I have many other lights. They also don't heat up like other lights so they seem very safe to leave alone or to hang around art and textiles. If you're looking for a steady long term relationship with a simple string light providing beautiful ambiance, these are the ones. I'm certainly buying again.
