These lights worked perfectly for what I purchased them for - as part of the backdrop for my Christmas pictures. They are a great, long length and width and shine brightly, but they are not overpowering. I had no issues stringing them up at all. They have a steady on mode as well as several different blinking modes. My only complaint is that the plug did not fit into my standard outlet - it was very loose and kept sliding out, so I had to tape it in to use it. Also, there is no off switch, so these have to be unplugged when not in use. Like I said, though, they worked great for my intended purpose.
