I used to have a round, smaller can from the same company and it broke after years of using it.  This one is so much better because the opening at the top is larger and, even though it fits in the same place, it is deeper. The shape makes it fit so much more in the can and makes it so much easier to take the bag out when it is full. I searched a lot of different sites and looked at a lot of different types of cans. This one is perfect for my needs. I Love it.
