Shower Bathroom Kitchen Floor Drain Anti-backflow one-Way Drain Valve Under The Water Pipe core Magnetic Drain Plug Drain Plug Oversized (1.2-2 inch Hole)

I liked it but it was to big for my sink

I really wanted this to work to aid in the wafting sewer smell that occasionally comes from the shower drain. After I removed the grate on my existing shower drain, I was going to test the fitment; unfortunately, it fell apart and literally 'went down the drain'. All I have remaining is the additional rubber gasket, and the strainer. The rest of the product tumbled into and down the drain. I am really hoping it flushed itself all the way through the plumbing pipes. Fingers crossed! Use with caution when preparing to see if it fits.

Needed to return. Both units I bought did not fit standard bathtub or sink drains

If smell is your issue, It definitely works. Be advised that you will need to clean out the “catch” every 2-3 months;This is not a one and done device.I recommend replacing it at one year for best results

I bought one, but it's too little, I couldn't use it.

Este producto lo compre para el lava manos del baño pero no quedó

Does not fit as advertised. There are better units on Amazon for just a little more money. I returned it and bought one of those which has been working fine.

Works good and problem is gone.
