Product review (3 stars): So So Stopper
I like the look of this stopper being stainless and I can leave it in the sink, without having to remove it to drain water. Which is the way we use it 90% of the time. So we basically leave it in the sink all the time.
We just bought new Quartz counters and stainless steel sinks and this stopper matches well.

My only negative on this product, is that when the stopper is open as shown in the picture of the product in Amazon, the center section flops to the side. It doesn't stand up nice and straight like the picture shows. So when opening this stopper the center knob flops to the left, right, whichever way gravity pulls it. It tilts about 10 degrees. It just doesn't seem high quality. It kind of looks like its broken or worn out when viewed in the sink.

On the other hand, when it is closed it holds water well with no problems in my sink. I noticed other reviews that had problems holding water, but not in our case.
