I have had mine two years now, constant use. I would highly recommend, I did have a slight leak issue but it was due to a the cheap hose i bought to go along with the bowl. Upgraded hose...no issues now.
It leaks where the hose connects to it. Also my float valve obviously doesnt work because it overflows and wont shutoff. I didnt like that I couldnt flip the top up to clean inside either.
I breed German Shepherds & Dog boarding kennel. I have been extremely happy with these bowls. But more over the customer support I received from the manufacturer was exceptional. These bowls are great for the 1 dog family to the Large Kennels, easy to clean, last a long time and do not rust and best of all the float is a better design than most of the automatic bowls out there. I also like the large size of them.
