I also have this well and when he came was a corner broken off from the base. Transport damage ... No matter is back intact ;-) The built-in low battery China with 1.200Ma I have removed just before the first use and replaced by Energizer AA 2500 mA.
The fountain does what it should ... it bubbles to himself ;-)
Only 4 stars because: 1.- Cheap Battery's are installed (otherwise it would become 5) 2.- the weight is too low, stable it is only through additional weighting in the foot ...
