UPDATE May 2022 - Had this for 21 months and Water Reservoir Basin is FALLING APART, - Now USELESS - Seams are leaking and won't hold water.  You'd like to think something that costs nearly $500 would last TWO YEARS - NOPE... Got this to replace a fiberglass one in the same location - Looks very nice, sound is very soft and pump is nearly silent!  Bottom is real slate, top is hybrid mix of slate and fiberglass & resin, looks good and parts mostly match - Assembly was easy, but the box was very heavy - Well packed and arrived in good shape - 1st shot is in living room, and then my "backdrop" in progress - 4th shot is final result - Negatives: Cost considerably more than similar sized nice fiberglass ones, often out of stock, and only holds about ONE gallon of water = Fill DAILY in Colorado - Have not let it run dry, so don't know about safety auto shut off if no water... - Simple enough to take apart and store water holding parts inside for Winter = nice - 4.5 stars if it were an option
