Product review (1 stars): I wouldn't waste my time purchasing this one and when it is ...
After being installed for 5 months, the inside is chipping and the chrome is showing through.  Now we have to purchase another 3- Bolt Mount Sink Flange and hire a plumber to replace it.  I wouldn't waste my time purchasing this one and when it is removed I'll return it. Definitely not worth your time or effort.
