Product review (4 stars): Verify your sink opening size
This seems like a really good product, but be careful on the size. I thought it would fit a "standard" sink drain, but either ours or this is not standard as it is about  of an inch too large and will not fit down into my opening without buckling. This made me very sad. I'm going to try to return it, but my son massacred the packaging when opening it for me. I'm not expecting trouble but will keep you posted.
