### ⭐⭐⭐⭐⭐ Just what was needed
*by C***R on October 13, 2023*

This part as was just what I needed, and the fit was perfect also very easy to install. Thank you.

### ⭐⭐⭐ Take two measurements before you buy.
*by E***N on March 22, 2025*

Before you buy, take to measurements. One of the sealing surface this is the measurement provided about the product. The other measurement is the attaching ear spacing. The sealing surface measurement was the size I needed, but the mounting ears were at the same distance and would not install on my toilet as it requires a narrower ear spacing.
