## Customer Reviews

### ⭐⭐⭐⭐⭐ Very high quality. Used for aluminium pole repair.
*by D***E on 29 January 2025*

I had a snapped and bent aluminum boat canopy frame which I had straightened and repaired with tube inserts and rivets. Fine as far as it goes but I had the bright idea of encasing it in heat shrink to prevent any rough spots damaging the canopy, and to disguise the agricultural nature of the repair in general.I tested several different types of heat shrink, and this one is the clear winner. It is nice and thick, looks great, and I was able to shrink 5 metres of it with a blowtorch without scorching it at all. Add to that its excellent substrate of hot glue, and it's even strengthened the poles somewhat by laminating them. I'm absolutely delighted with the result, which would not have been possible with an inferior product.

### ⭐⭐⭐⭐⭐ Excellent Adhesive Heatshrink
*by M***S on 18 August 2023*

It works exactly as I hoped. Some reviews said that the tubing walls were very thick but I found them to be perfect and actually thinner than some other tubing I've used. I also noted that it does a genuine 3:1 heat shrink as well. Very happy and highly recommended.

### ⭐⭐⭐⭐⭐ Great heat shrink
*by A***. on 20 October 2023*

Amazing heat shrink, takes a while to get around 16 guage but it does fit. And the adhesive really seals it up, I tried pulling it off my test wire and it actually too the wire insulation with it.
