High Quality Heavy Stainless
I needed a set of bowls (I got the large for water - our dry climate necessitates plenty to be available-- and the small for food) that were square to fit in a small space where we would not trip over them. The large fits in front of my dishwasher and is low enough that I can open the dishwasher without disturbing it. The small is a few feet away inside a threshold where we will not kick it. The only feature I did not realize it had was that one side of the bowl is lower than the others. If you're not careful, you could look at the high side and overfill with water. This has not been a problem for us, but is worth noting. These bowls are very high quality stainless with a rubber-type bottom that keeps them in place. This was my first order from PetGuys and I was astonished at how fast it arrived--I ordered on Tuesday and it arrived on Friday. My skittish red heeler had no hesitation in using them the first time.
--Dog accepted them readily
--Extremely fast shipping
Cons--One side of bowl is designed to be a little lower than the other sides. This is by design, but I did not realize it from the description. However, I still would have bought it for the shape I needed, the size, and the price.
