## Customer Reviews

### ⭐⭐⭐⭐⭐ Ignore The Beige Color, It Works
*by D***5 on February 22, 2021*

I wish it came in clear or even black. The bottom line is my 2-line rj11 phone cord stopped working on my Uniden Dect6.0 phoneI plugged this cord into my outlet and voila! Line 2 was back up and running problem solved

### ⭐⭐⭐⭐⭐ Just The Right Length...
*by P***. on June 13, 2018*

Perfect for my application...Well made and works as expected - eliminating all the down time caused by a speck of dust floating in the communications closet and bumping into the Geri-rigged old setup. (HA ha!)Highly recommend (give yourself extra slack,you won’t regret it)SEMPERFIDELIS

### ⭐⭐⭐⭐ price is right
*by C***E on January 7, 2019*
