I love it and so easy to assemble! The fountain started to work almost instantly, as soon as just a small amount of light hit it. The brighter the sunshine the better the flow. I had birds the next day.
I filled the pedestal with pebbles for added weight as water leaks out base. If you use sand, try adding water after to absorb and make heavier. I have sandy soil, so the anchors don't work that well but are better than nothing. 
Another tip: Make sure your birdbath is level as it will hold more water.
Highly recommend for an inexpensive way to brighten up your outdoors.
