This product is extremely light but surprisingly sturdy. At first I thought the stainless steel bowls seemed thin and flimsy but after a few days I found the concern to be unfounded - it's much easier to clean and stainless steel is more sanitary. Inexpensive and very functional - our little dog does seem to find it easier to eat and drink from because he doesn't have to bend down (try swallowing with your head bent down below you stomach and you'll realize just what you are asking your dog/cat to do when they eat).  Our dog stands about 19 inches tall (from head to foot) and we ordered the meduim size which seems to fit him well.
