I bought this adjustable dog bowl set with the 5 quart bowls because we have two large dogs. I chose this style because we also have a jack russell and I figured we could fit his bowls underneath. That part works great for space saving. The rack is sturdy enough, but I've found when you fill the bowl with water, it leans over because obviously, water is heavier than kibble. I even tighten the knobs as tight as I possibly can but it still lists to the left. Also, one of the bowls came with a huge dent in it, but that didn't really bother me. The stand has two separate knobs: one to hold the rings that the bowls go in, and one you put on top of the bowls to keep them in place. THAT part is a little inconvenient because you have to unscrew the knob just to get the bowls out. But I completely understand the purpose of it, so that's cool - just trying to give a thorough review. All in all, I am happy to have purchased a product that elevates the food for our large dogs, and happy that it is not a bulky stool type stand, so would recommend this to others. I bet the bowl wouldn't teeter if it wasn't the 5 qt size (which is the largest.)
The set up was problematic. You need to remove the height adjustment screws every time you want to remove the bowls and it's a pain. We finally just took them off completely. The weight of the water made that bowl tilt so we had to put in a shim. Now the other bowl is tilting as well. We have a very tall greyhound and he needs to have his food/water raised and this looked like the perfect solution. Alas, with tweaking it is working although we now have to add a second shim on the other side. I can't imagine what the people who came up with this design were thinking!
Perfect for our older dog. He had a hard time bending over as he's getting older. He was losing weight because it was difficult for him to eat. Thought we'd give this a try and I'm glad we did. It makes it so much easier for hima nd he's gained his weight back and seems a lot happier....and so are we!
