Same problem as anothet one. Misleading name. These aren't pop up as in you push the drain down in the center and you either stopper the water outflow or open it up. It's a traditional drain that requires the hole in the back of the faucet to push the lever. I will be returning this.

Very well built product and super fast shipping as always!

I purchased these drains for my new sinks going in my master bath. I haven't installed them yet but they seem very sturdy and way better than the plastic assemblies that come with most faucets.
