I've used a lot of sink stoppers before using this one, and this one beats all ! IXO Good Grips Sink stopper is the best I have ever used. I love the fact all I have to do is turn the inside knob of this stopper to either stop the flow or drain the sink. And it's leak proof. No more loosing my soapy water in the middle of doing the dishes or cleaning the refrigerator. It works!!!
