I was able to assemble in about 15 minutes. The product is plastic made to look like stone but not too heavy for me to handle. The molded pieces did not fit exactly as they were suppose to when twisted together but no one would know looking at it fully assembled. The molded holes that let the water flow from top to bottom are not consistent in size so some flow well while others drip..but again, this was not a deal breaker. Overall, it works well, lights up at night, has a nice water sound, and it a nice accent in my yard. I think the price was pretty good too compared to local garden stores. The solar panel is about 5" x 7" and black with a cord and needs to be hidden somewhere yet getting direct sunlight. The unit does not use electricity at all, only the solar panel.
