This pops right in and appears to be made from a high quality material however it's a hindrance to proper sink use. Like most of the other reviews my sink flow is suffering greatly from this new baffle. I purchased a disposer and this baffle came with it, I wish I had kept the grungy old one even though it was ugly it worked this one doesn't. You have to manually push open the baffle to allow anything to flow freely into it including water. Just running the faucet causes the sink to fill because the flow into the disposal chamber is so slow. The noise with my new disposer is so quiet it would be better to run it without the baffle except for the obvious danger issues. LOVE the disposer HATE the baffle.
