It is quite confusing to put together at first (several pieces to put together), but it is a nicely made product overall.  The ceramic parts of the piece is a nice feature.  The pump/motor is very quiet, you don't actually hear it all.  The cats are scared of it at first, actually hissed at it, but they are warming up to it.  May be too soon to tell (it's only been 5-7 days) to see if they will use it.
