Big mistake

I learned how to use it from this site and tried it on and odd connector that needed repair. Got it to work, but not sure how long it will last. Does not shrink like the tubing does. May have better luck next time using a sliced piece of large tubing instead of this tape. If it had adhesive, it might work better, get the benefit of ordinary tape with some shrink wrap.

I bought this tape to repair some headphones whose insulation had cracked. Since I couldn't disconnect either side, regular heatshrink wouldn't work -- I couldn't slide it over either the headphone or the jack to the affected area. I bought this product thinking it would be like electrical tape that would shrink when heated, but it is not. It is very thick and inflexible, approximately 1 mm thick, and it cannot be wrapped around anything thinner than your thumb. In addition, there is essentially no adhesive on this tape. It won't stick to itself, nor will it stick to much of anything, so to use it you need to quickly wrap it over itself and then wrap electrical tape around that. It will not adhere to the underlying cable very well, so you'll often end up with a tape tube that is much larger than the cable & it won't shrink down correctly.

Until I need to wrap heatshrink around a 2" electrical cable, I have an expensive paperweight. I had better luck taking regular heatshrink tubing, cutting a slit down the middle and twisting that around the headphone cable. I'd recommend that approach, instead of buying this product, for anything less than an inch in diameter. It's a great idea and a great disappointment.
