More like a 3.5 star.....I love everything about it, the look, the color, the size of the bowls...but the height for a medium size dog is just not tall enough and that's a pretty big flaw for us. : We also ordered the small one and it's absolutely perfect for our little guy. But this medium size one is still to short for our boxer (small-ish boxer, she hovers around 50 lbs)
