I purchased two of these nice looking feeders three months ago for my two 60 and 80 lbs dogs.  I liked the overall design from the pictures on Wayfair.  When I received them, the construction of material was much smaller in diameter than I thought it would be and measured 38” (9.5mm).  I was still happy with the purchase when I put them together and they provided a nice clean look.  However, both have started to rust on the set screws used to put them together and also at the various joints and feet.  Obviously, the materials used are not very moisture resistant and I am disappointed in how fast they started to rust.  My dogs are pretty neat and rarely even get dog food on floor.  It is impossible to keep water out of the hex screw caps and away from joints when they drink.  I like the way they look initially but don’t appreciate how fast they rust.
