## Customer Reviews

### ⭐⭐⭐⭐⭐ Seems sturdy
*by T***. on September 17, 2024*

I used these, together with sections of pipe, to house mason bee nesting tubes.

### ⭐⭐⭐⭐⭐ Great product
*by D***R on December 24, 2019*

This robust flange, which Amazon sells for 2/3 the price that I would have to pay for at a giant national hardware chain,is a premium version of an all plastic equivalent. It provided my toilet with a rock solid mounting foundation and its stainless steel ring would be very long lasting in a moist and corrosive environment.

### ⭐⭐⭐⭐⭐ Could't Use it but...
*by A***R on August 16, 2018*

Purchased to fit inside a 4" drain pipe but doesn't work. It actually has a 4" opening and fits over a 3" pipe. Its well made I would recommend it. Got a full refund. Thank you
