Product review (3 stars): Fits my drain perfectly. Doesn't allow good water flow.
This part fits perfectly in my sink drain. 3" in diameter. The ones they sell at Lowes or Depot do not fit sinks made for GE disposals, so this was good for that purpose. It appears to be a durable part that will last a long time I'm sure. My only contention with it, thus the two star deduction, is that the water doesn't flow through it well at all, as many other reviewers have also stated. Even with the faucet turned on to half flow, the water pools up in the sink and takes a long time to drain through this part, which is a pain if you have a bunch of crud in the water from rinsing dishes. There are little rubber skins between the grooves that go from the center hole to their individual small holes on the outer. Some of the little holes also have this rubber remnant. It's like a leftover little skin from the likely injection mold process used to make these. I spent over an hour with my xacto knife cutting away these little skins, and making the center hole and all the small holes a little bigger. The water flows better, however, it still pools up a little when I have the faucet turned on full. I don't want to trim more because I don't want to lose the shielding from grinding food bits in the disposal that this part is meant to provide. So I guess it's a happy medium. Perhaps a different cutout design would provide ample water flow while maintaining a good guard against flying bits while running the disposal. It's too bad because there doesn't seem to be any better options out there for the GE size drains.
