this is an exact fit and it is nice to know you can replace some of the parts to this product since the initial cost is at the high end.
Love that these are replaceable by annac03/20/2012
I'm a forgetful person so I've probably forgotten to check the water level too many times & burned the pump out. But I would recommend this fountain to anyone. Both my kitties love it, it's quiet (pretty much the only sound you hear if the water fall), but like I said make sure to keep water in it or you will burn through the circulating pumps. It's great that you can get replacement parts though that helps a lot.
