Product review (5 stars): There are two different designs with the same model number
There are two designs. I went to Home Depot today and in identical packaging there are two different baffles. One has a much smaller hole and two cuts in it (rectangles) as pictured. This version is terrible. It drains very slowly and food has to be pushed through. This is the original version that came with our evolution. The other version has a larger hole at the bottom and no slats. This version does not have any troubles draining at all.

I suspect they went back to the less complicated design. It's probably a bit louder, but fed up with a slow drain I'm happy I can get the older style again.
