I have an older home & no dishwasher, so I needed a good replacement for  my drainer stopper that was leaking, I bought a replacement from hardware store, but was a bit too small, & also leaked. Very pleased to find this one by OXO. The over size collar covers the whole drain, when  locking down it doesn't leak. The fine holes of the strainer trap everything. Very pleased  with it & highly recommend if any one needs a replacement. And it's attractive too.
