Query: not happy with this product

I purchased this items twice and it was defective. The first time the cobalt blue pots were broken during shipment. The second time when I assembled the unit and place the water pump in the water (submerged accordingly) the pump fell apart and could not be reassembled. The pottery was beautiful. I do think the fountain was overpriced for its size and durability.
