Question: how do you install this drain?
Document: Easy to install and work great. Used the drain in three sinks and was very pleased. I would recommend them for anyone installing a vessel sink
the sink drain was perfect - easy to install and looked great with the glass vessel sink that we also got from Amazon - thanks for recommending it when we ordered the sink
i gave this a 3 star cause the description in incorrect. it says that this is a brushed nickel piece, however the top push piece IS brushed nickel but the bottom  piece IS NOT, its polished chrome. i had to install this in a customers house. i had to spit some bs how that's the way they all come after i had them all completely installed. thank fully he said its not that noticeable. its a good drain works fine. i would recommend if you know that the drain itself has two different finishes.
Again had to have this to install the sink which did not come with anything but the bowl. Works fine and I have no complaints.
This was as described and works well. No instructions but was pretty easy to install. Definately happy with the purchase.
Thees fits perfectly with the vessels we bought them for. Well made, arrived quickly, and were easy to install. They work well and we liked them so well, we bought more for our other bath. Great product.
I took that as a good sign, and am now very happy with the Inello drain.)
I have better things to do than replace a drain in less than 2 months time.
This  pop up drain works just right with the Decolav Sink,the push it down push it up is great.no messing.
The lavatory Vessel pop-up drain is a GREAT addition to my Vessel sink. I'm so loving it!
