## Customer Reviews

### ⭐⭐⭐⭐ Four Stars
*by L***1 on January 29, 2018*

A necessary product that works as described.

### ⭐⭐⭐⭐⭐ Exactly what it's supposed to be
*by P***E on March 14, 2014*

The product was exactly what it was supposed to be, the color was a brighter blue but this isn't a show piece of any sort and was functionally perfect

### ⭐⭐ Does not fit a 2 inch double check.
*by D***L on January 19, 2021*

So the description says, and I'll copy and paste it in here. ( Designed for use with 1/4" thru 10" Model 975XL, 975XL2, 375, 375XL and 475 Reduced Pressure Principle Backflow Preventers on horizontal or vertical installations. However this one only works on the 1 inch units. the opening is too small by nearly 1/4 inch. Just wanted to let anyone know that if you are ordering this for a 2 inch Wilkins double check, it won't fit. Most of my double checks are the 975 XL units.
