*by W***N on Reviewed in the United States on May 10, 2024*

The bumper balls worked well enough for the intended purposes, don't know if these would hold up for professional use, but, they worked well enough for running cat6 cable in my house that was built in the 1960's, we ran networks drops to 3 bedrooms and into the living room.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Recommended for drilling inside walls
  

*by S***N on Reviewed in the United States on May 25, 2023*

Needed to run romex up a wall into my attic. I bought a flexible extension and self feeding drill bit. Before starting the project I thought how do I prevent accidently drilling through the wrong place. I found these and they are the balls! Easy to install, and they work flawlessly!
