I am somewhere between a 3 and a 4 on this one....
The good.... very heavy and rubber feet so pupper can't push it anywhere. Also, the bowls have a rubber underlining that keeps it steady and quiet in the stand.

The not so hot..... its not the size it says on the ad... its only 17" tall not 18" as advertised (that's a pretty bad error for an online product).
 May not keep it because it isn't quite the right size for my dog.....
