Pros: Glass is safe to drink out of. The stainless steel top is also safe. Pump is very quiet and the rubber bottom keeps the fountain in one place. The cats love it.
Cons: The blue light on the pump cannot be turned off. I had to wrap black cardboard around the glass to keep the whole kitchen from being lit up blue all night long. Cats are very sensitive to blue light. Also, the steel top tends to develop a hum from the water pouring into it. Kind of like a drum effect.
I'm sure that NPET will address these topics in the future. They make a great cat fountain and I would recommend this item to interested people.
