Review: Works - Used these to repair some lightning cables and an old 90 degree MagSafe cable. The lightning cables fixed easily and completely. THe MagSafe end was too big to fit the largest piece around, so i cut it in half and tried it that way (obviously not how you’re supposed to apply heat shrink). However, the adhesion was good enough that i was able to fold it over itself while shrinking and shore up the cable. It’s held for a month so far of daily use, and I’m super satisfied.
Review: It's about time!! I can use every tube! - It's about time a company put together a fully useable assorted mix as these shrink tubes! I can't count how many of those so called "assorted kits" of shrink tubes I have bought only to end up throwing away or losing 30% of the box. This kit is the perfect mix of tube sizes for real world use. If your wiring or soldering human hairs or nano strands of wire(no real man does) then you don't mind getting those kits with tubes so narrow that air barely passes through. This kit is for a real world guy who works in real world situations that require a great variety of wire joint protection. If you like throwing away money on microscopic nano tubes buy the usual worthless kit. If you want to be able to use every single tube and work with something useful, durable, easy and does what you expect it to do....buy these! I know where I'm buying my next box. Real men control, harness and conduct electricity. The rest throw their money(and useless tube) in the trash.

## Questions & Answers

**Q: Why are some reviews talking about wire? Is this for heat shrink tubing or wire? Or has amazon got their reviews all messed up again?**
A: Go back and look at the Amazon page for this, It has multiple options to choose from. From 18 to 30 gauge wire, and 2 different heat shrinks 2:1 and 3:1. So depending on what you wan, you have 8 choices. Click on 2:1 heat shrink and that is what you are buying. I agree, when I read a review I want it for a specific product, Not several different products. But this Amazon page lets you choose which item you want to buy and then the reviews are all thrown into the same pot.

**Q: Why is the vast majority of questions and reviews here referring to "wire" when the item is shrink tubing?! Sounds fishy to me. I'm going elsewhere.**
A: I came to ask the same thing, but Im pretty sure its marine heat shrink, which is relly good stuff if you need thicker heat shrink with an adhesive inside. I ordered it anyway.

**Q: Does the adhesive work as a conductor or as an insulator?**
A: Im pretty sure its a thermoplastic adhesive. It would be non conductive until its dielectric breaking voltage. Which is likely very very high. Like in the ranges of 100,000's of volts. Example 100 - 300 kilovolts per centimeter area.

**Q: does this have adhesive inside the tube? or just standard shrink tubing?**
A: From the information provided by the supplier: See below.
Safe & Easy Used: Our heat shrink tubes has the advantages of good electrical insulation, good tightness and corrosion resistance, high temperature resistance. Cover the bare wire part with these tubes, heat it with soldering iron, heat gun or even hair dryer , the tube will shrink protect the wires and give you a professional look of the repair job! Note: Make sure temperature of your heat gun is up to 212℉(Fahrenheit), then glue inside will soften and seal the connection.

### ⭐⭐⭐⭐⭐ AAA - Product thumbs up for me
*by M***A on July 19, 2020*

TUOFENG Heat Shrink Tubing I would recommend this product! Good Value, at first I was not sure they had adhesive inside, you cannot see it. But after a closer look after I completed my wire harness it was in there. I was expecting it to be oozing out but it just perfectly sealed around the edges. Paired with the Amazon Recomended Genesis Dual-Temp Heat gun the tubing shrank evenly and quick. Don’t listen to the bad reviews on this one, if you use a lighter expect to burn and ruin it. Its heat shrink not burn shrink Don’t use a blow dryer its not the correct temperature or air flow - your shrinking, not drying! If you are disappointed with the sizes and colors I’m not sure why because what I received is exactly what was described in the listing and performed well.
