I have been in search of this set for a reasonable price for quite some time. The raised sides, and anti-slp base are 2 things that I really needed. The water bowl compartment comes with a complete water bottle system that self replenishes and doesnt make a mess. There is a raised center that makes it hard for the pets to get food mixed into the water. I have taken this apart to clean it and find it very easy to clean and put back together. This dispenser is great for 1 or more pets, and is small enough to replace any other system that you may be using now.
