These are wonderful bowls, with a good pitch and heavy gauge aluminum. The main selling point, though, is the rubber coated bottoms. The bowls grab onto your counter as you whisk, stir and mix, never giving up an inch. Here’s the rub, when you put them away in your cabinet, that rubber doesn’t stop working. And, you thought they did a good job holding onto your counter? They glue themselves to the painted shelf in your storage area, lending themselves to a very dramatic next appearance.
