I was having trouble with my metal drain stopper not holding while the sink was filled. I got the OXO drain stopper. It works great, but also has some fun and useful features. I love that you can empty the sink with the turn of knob. It lets the water down so gently that I don't get a loud gurgle from my double sink like I used to. Just note that you have to turn the knob all the way to the left to keep it open or the water pressure will close the drain again. You can also take off a cup on the back to keep the drain open. The best feature is being able to push up on the bottom to pop the strainer inside out for effectively dumping food scraps into the trash. This product is easy to use and easy to clean. I will get another one for my other sink. Also, my sinks are older and this fits great!
