Review: Solid fix after years of throwing repair pieces at it. - My advice would to pre build it before attaching it under the sink. Also there is a cap that can be used to block off the vent for a invented sink. The baskets in the sink are nice and deep with strainers. Big plus. The caps while just using a little rubber ring to seal are watertight and holding up well. But I expect they won't last too many years. The cup in the trap is a neat novelty, but doesn't see anything due to the strainers in the sink brackets.
Review: Just what we needed - Our house is from the 1800's and trying to find replacement parts for when things go kaput is next to impossible. After trying to repair our kitchen sink with packages, it only lasted 5 months due to things not linking up properly and poorly shaped. This solved all those issues! Super easy to install where we needed it. The overflow is not an issue for us, we simply secured it up on the air under the sink. We will figure out a way to cap it off, if needed... but for now it's working perfectly. Being able to adjust it how you need it was an absolute gamechanger and saved us from having to call someone.

### ⭐⭐⭐⭐ Doesn't extend 20 inches
*by M***E on November 10, 2025*

Seems of ok quality. Unfortunately the website says it extends 20 inches. It does not. Id say max 18 inches. Used a 1-1/4" to 1-1/2" furnco to attach and lengthen the center pipe. It worked then.
