I really like solar devices. I have numerous type like flowers, lawn lights, pest deterrent flashing lights, and star bursts. When I saw these I had to get them. They are easy to assemble. The come in three piece - the lights and solar collector section, the tubular extension and a pointed spike end for the extension. They all slip together. Place them in a sunny spot, flip the on switch/button, and come nighttime you have a fun flashing or steady multicolored light device. I have them lol over the yard and it's a fantasy land night. My wife thinks I'm a little crazy,I'm in my 70's, and she might be right. But when all the lights are flashing, it makes me happy. I recommend them.
