Solid choice. I was making a light project for the wife and needed some heat shrink I could place over the wiring so it looked less DIY. This was the perfect choice. I was able to cut the length I needed, slide it over the wires and then heat it to a nice snug fit using my heat gun. The 1:3 shrink rate is highly accurate and my only suggestion would be to cut less than you need since it will extend as it shrinks. Overall, easy install and great value for the money.
