Review on U S Standard Sink Push Drain by Matthew Baltimore

A little difficult to install in the drain for the first time. Once attached, it unscrews for cleaning and keeps the water in the sink perfectly! I haven't had enough time to learn about the durability of the materials, but they appear to be well made. I would like something similar in a larger size for the bath/shower drain. The hair is cleaned really well. As a senior, the device is easy to unscrew, and that's important. I love not having to struggle with the plunger at the back of the faucet that always unscrews and has to be reattached under the sink! Expensive but if it works and works then it's worth the money. Rating of this product for the elderly!
