Query: larger size doesn't have enough support

I purchased 2 of the 30 oz cups for my dog's crate. Each holder only has 1 bolt and wing nut, which I should have realized in advance would not support the larger sized cups. Between the weight of the food/water and the pressure my dog would put on the cups while eating/drinking, they didn't last 2 hours in the crate with my dog. One of the wing nuts was stripped when it arrived, so did not hold up at all. The other one I put in my bird's cage as a bird bath. I gave this product 2 stars because the description is not misleading, but one of the two I purchased was pretty much worthless. Instead, I purchased 2 of theMidwest Stainless Steel Snap'y Fit Water and Feed Bowl, 2 Quartand they work great. I guess you get what you pay for.
