    Works like a champ
  

*by M***Z on Reviewed in the United States on July 19, 2024*

Been a fan of 3 to 1 shrink for a while. Wanted to try 4 to 1 in a few applications where 2 layers of 3 to 1 were needed. This stuff did it in one layer.

    Fixed a thunderbolt cable
  

*by M***Y on Reviewed in the United States on October 23, 2020*

I tried to fix this cable with a different heat shrink tubing.  That tubing had a shrink ratio of 2:1.  If you use a diameter large enough to fit over the thunderbolt connector, the 2:1 shrink would not shrink tight around the cable.  This tubing is a 4:1 shrink ratio and it worked perfectly.  It also has some glue inside the tubing which will glue the shrunk tubing around the cable.  Not sure I need that and would make it difficult to remove if I had to, but now that it is on, the glue really makes it a solid fix.  I also used Bondic inside the tubing to seal the split cable insulation.  Recommended for any application like a cable with a connector that you need to pass over.

    Works great, and like adhesion
  

*by M***. on Reviewed in the United States on April 30, 2020*

I used the 8mm tubing on my macbok pro mid 2012 charging cabel, which had the rubber exterior starting to peel off at one point near the adapter at the computer end. Slid it over the adapter to rest on the failing cable section, and shrunk it down. Now a repaired and stronger cable, and looks clean. I specifically got this for 4:1 ratio, so that the 8mm would shrink down to the 3mm cord. PERFECT.
