Assembly was easy. We let it store sunlight for the first day and then turned it on the next. My wife loves it. The only thing I would say is we mainly use it as a bird bath since we cannot leave it running. The water goes over the sides of the bowl even with the slightest breeze so it empties itself after just an hour or two of running. If the bowl was a couple of inches wider it would be great so it would not spill everywhere. I did level this so it is not that it is at any type of an angle. It does go in the bowl as long as there is no breeze blowing. We turn it on when we are outside on the Patio grilling and that is good enough for us.
