The cover rotates, not the dish - so the unit needs to be placed so your dog can reach it from all sides. This doesn't work in my kitchen, I feed my dog at the end. It is also somewhat small. I have a small yorkie who eats 1/4 cup of small kibble. This unit would work for that quantify, if you have a bigger dog I don't think it would work. I'm returning it. It seems sturdy, so if the design works for you I would highly recommend it.
