Nice sound, definitely can be adjusted for flow. Really pretty fountain. The packaging was a bit iffy- otherwise I would have ranked this a 5 star. Edge of container was nicked and one of the cups metal was slightly damaged.  That being said- It worked perfectly and I wasn’t going to return it. Definitely need to buy rocks separately to cover the bottom. Fairly easy to set up. Place it where you want it to go before filling it- way too heavy to move without draining it first. Really a very pretty fountain.
