This is basic and super easy to use. There are 5 parts. A floater ring, a bucket that sits in the ring, a light/fogger with power cord attached, that sits in the bucket with the cord coming out of a notch in the bucket, and an umbrella splash guard that you connect to the bucket by placing a shaft on the umbrella into a hole on the rim of the bucket. You put water in a container and float the fogger in the ring in the water. Please refer to my video for information on this. In the video I forgot to mention about putting the light into the bucket, so don't let that confuse you. The fogger assembles easily and starts working immediately when plugged in. It has a two prong plug, and both prongs are the same width. It's small, so don't expect it to do the job of a larger unit. It makes enough fog for one container, not a large area. The lights change color, and cycle automatically through the colors. There is no control for changing colors or to turn the unit on and off. Plug it in and it starts, unplug it and it stops. I gave it five stars because it's a small, basic unit, and it does its intended job well.
