## Customer Reviews

### ⭐⭐⭐⭐⭐ Alumacon
*by P***P on January 7, 2026*

Working well.

### ⭐⭐⭐⭐⭐ Great item!
*by D***E on December 21, 2025*

These are great for homes that have old aluminum wiring. The twister have penatrox inside, so no mess!

### ⭐⭐⭐⭐⭐ A total must with the new light fixtures
*by M***S on October 10, 2023*

I am an electrical and lighting engineer. Most new light fixtures use aluminum instead of the traditional copper which is used in existing houses. Why you ask? Aluminum is cheaper. BUT that complicates things & the importance of this wire-nut cannot be overstated. When you have the termination of two different materials you need to use the proper protection. This wire-nut emits a clear coat onto the wiring to ensure arcing doesn’t happen. Very cool device, while a bit pricier, well worth the piece of mind to make sure that new light fixture you’re installing doesn’t burn down the house ☺️
