### ⭐⭐⭐⭐⭐ 







  
  
    Awesome heat shrink!
  

*by P***N on Reviewed in the United States 🇺🇸 on January 10, 2023*

I ordered this to make 4/0 battery cables for my RV solar system. I accidentally ordered the 1" instead of 3/4" and it still worked perfectly fine. Seems solid and thick so far, hopefully it will keep my cables protected for a long time. 5 stars!

    Awesome for Christmas lights!
  

*by M***N on Reviewed in the United States 🇺🇸 on December 9, 2022*

Every year during Christmas, every time it rained my GFCI would pop and the lights would go out.  Since I've used these on all the extension cords and lights, my Christmas lights have stayed on even in the rain.  I wish they were slightly less expensive, but it does the job well.
