I got this a couple of weeks ago hoping my kitty would use it. It took her a few days to warm up to it. The assembly was simple but the top part doesn't go into the connector tube for the pump the way I would have expected. It isn't a tight fit. I also wasn't expecting the size to be so big. This thing is the size of a huge metal dog dish for really big dogs. It holds 128 oz of water. I also needed to get a waterproof mat for the Fountain because it makes such a huge mess. I had to put it in my bathroom because of the size and mess. I like there is an attachment to give different amounts of flows for the water but right now I have it on the 2. My kitty drinks both out of the bowl and from the streams. The water splashes out from hitting the metal cone. I have to add water every other day. They also recommend to change the filter every two weeks but it only comes with 1 filter.
