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.
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.
