My cats instantly took to this water fountain. I like the water fountain as well since it is so much easier to clean than the 3 previous fountains that I have tried. I like that there is light indicator that reminds to me to fill the water and a different color light indicator to let me know when it is time to change the filters. It has been about 3 months since I purchased this water fountain and have 0 issues with it. It is easy to fill with more water, it is very quiet, and I like that it only runs as necessary. I use the smart mode. I have recommended this fountain to my friend who has seven cats, however, for that many cats, she would need more than 1. I currently have to add water once at the beginning of the week and then about 4 days later (one of my cats has hyperthyroidism so she drinks a lot of water).
