We received the fountain about 2 weeks ago and so far we are quite pleased with it.  It works great.  We have it set in the middle of a flower bed and it looks beautiful.  There is sun there most of the day so the solar works perfectly.  We have had an occasional cloud or two but once they move away, the fountain starts up immediately.  We have tried putting it on battery during the cloudy times to test it out and that also works perfectly.
