I received this in about a week. It comes as just the item--no box or instructions.
To make it work, put the lid on the container, then turn it upside down and fill the container with water through the little hole at the bottom of the container. Completely fill the container with water, then--whilst the containter is upside down--place the bowl onto the containter, then flip the whole thing over. At this point, really push down on the lid to ensure it is tight--this will create the suction needed to make it work! Water should be slowly filling up the bowl, and the lid should sort of curve downwards in the middle which means the suction is working and the bowl should not overfill. It took me a few tries to get this to work properly, but now it works a treat!! --the trick is to really push down hard on the lid once you flip the whole thing over!! It must be concave in the center of the lid!! I'm pleased w/ it and my cats seem to like it. I was sent the bright pink one and it is a lovely colour, and looks just like the one in the pic! I'm so pleased, I will probably order another one to keep upstairs and perhaps a larger one for my dog.
