content: I have used this product for several months without any major issues. I would recommend this waterer to any potential buyers. It is sturdy and easy to clean. There is a gurgling noise when the water needs to replenish in the bowl. At first, the sound startled my pets but they are all accustomed to the noise. They adapted from a bowl to the waterer rather quickly. I have three of these waterers in my home. They are shared by three cats and three dogs.
