### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Rentenna
  

*by M***1 on Reviewed in the United States on December 30, 2016*

Antenna was a perfect fit and good quality.  It works to boost the signal to my cell phone while using the Renny device so I can hear my cell ring throughout my small house. Product arrived on day it was supposed to and was in excellent condition.

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Modest increase in range
  

*by V***L on Reviewed in the United States on September 20, 2013*

Definitely increases range of the Renny bluetooth remote ring/answer system.  I had hoped for even better coverage, so I'm not prepared to give it five stars.  However, it has made the device workable in my house, where the Renny itself, without the antenna was unsatisfactory.

### ⭐⭐⭐ 3.0 out of 5 stars







  
  
    Three Stars

Antenna did not help a hopelessly flawed product.
