Love everything about them! I actually had cars stopping in front of my house to look at them. I purchased the blue ones. I couldn't believe how bright they are. They can be seem 1/2 mile down the road.
I purchased 4, three were put on a tree in our front yard and the other on the front porch. I was worried about them getting wet, especially the main cord which has a box which runs the LCD lights, but they stayed on!
I have not taken the, down yet. I'm going to keep them up for a couple more weeks.
I have ordered 6 multi colored ones.
One yeah: When you start attaching them to each other, test them, each string you attached. The prongs have to connect in a certain way.
