This pet water fountain was super easy to set up following the included instructions. Once set up you just add the water and then plug it in to get it started. It doesn't take long fro the water to start cycling through the filter and for it to be ready for your pets to drink. We have cats and they love having the fresh water always available to them. It's compact and doesn't take up alot of space either. So far have not had any issues with the water fountain and it seems to be very well made.
