The popup drain comes with a gasket to give the sink a snug fit with the counter top. We should have measured the gasket and had the hole in the counter top cut smaller. When we installed the popup drain the hole in the counter top was just a bit too large for the the gasket to give the best tight fit we needed under the counter. This oversight was on us not the product.

Pros: Easy to assemble and all the necessary parts were included so installation was a breeze.
Cons: Be extra sure you measure the gasket before you cut the hole in the counter top!
