Once I received the package, it was running in less than 15 minutes. The sound of the water fall is very relaxing and it is setup in my backyard patio area. I spend most of the day outside in back, so it is a great benefit to me. I have to only fill up the reservoir once a week and turn it off at night before going to bed. Very happy with this product and it give enough light at night that I don't need the patio light on.

Pros: Very sturdy and colorful. Pump is very quiet.
Cons: none so far.
