Query: Nice---a Good Deal!

Very nice. It was a little tricky as it didn't come with instructions but I looked at pictures and figured it out. I, too, added more stones as I didn't get many stones with the purchase. However, I purchased some stones at the dollar store and they work great. I am experimenting with different amounts of water as I like the sound of the water trickle.
