I am really impressed with the quality and ease of assembling the Outdoor Deluxe Pineapple 2-Tier Waterfall Fountain. I hadn't unpacked and put together within a matter of a few minutes. The pieces are a lightweight resin fiberglass material. The first level  goes on to the base you turn it and it's locked into place,  second one you attach your pump  and slide it down, the very  top slides on, the pineapple head will go on next. When you go to purchase distilled water buy 3 gallons. It recommends distilled water but does not tell you how much. If you're looking for a easy assembly water fountain. I highly recommend this one. It looks beautiful and I love the peaceful sound of the trickling water. You also need to make sure it's on a level surface, I found putting a few pennies under 1st tier, where the pump attaches leveled it out perfectly.
