Sorry, I have not put them to use yet. But I can tell you what I like about them so far. I love that they are battery operated. Kind of forgot that until the arrived at the house. They are small and discrete as they can be tucked away and I don't have to worry about them dangling, which is what I don't want, especially for what I have in mind to do with them. They will be hung up around the upper area of my patio. This will give light and ambiance to the patio area. Can't wait until my project is done, hopefully I can submit pictures later. What a great find!!
