What I received was 2 of the 4 that were on my order. Since the plastic part is one molded piece, it's unclear how this is supposed to function as a backflow preventer (there must be some "float" component that uses the direction of flow to determine if the drain is Open or Closed). Perhaps the intent is to prevent sewer gases in case your plumbing is missing a p-trap, but it's pretty unlikely to work for that purpose either. It will slow the rate of drain if people have some kind of phobia about fast-draining showers/sinks, but I could just drop anything in the drain to obstruct the flow for that purpose.
I have purchased this item for my shower 2" drain. It got stuck inside PVC pipe and traveled down. Now I'm facing costly repairs of breaking tiled floor and PVC pipe thanks to this horrible innovation. Do not buy.
