Pros: Stays clean! Efficient!
We wanted dual flow toilets but couldn't find them at our local home improvement. (Hint! Try Costco) This was our greenest choice. It was easy to install in all but one of our bathrooms. That was a placement and former toilet issue. Checked the seals more than once. It doesn't seem like it will work there so little water, but it's AWESOME! Feel great about saving more than 1/2 the water each flush.
