I recently purchased this product to replace a different fountain I had been using for my cats.  I have several felines who love to drink out of the faucet and I thought this would be the "purrfect" solution for them and me.  Sadly, since the first time using it, the water flow never works on all the ports.  On the 4 port only 3 worked. ON the 3 port, only two would work.  If I pressed down hard on the top of the unit then all the ports would work.  The motor suction cups do not stay attached to the fountain floor and the motor moves all over.
