Appears to be good quality. Not easy to burn or burn with a heat gun. I've found that the glue holds better if I rub the wire insulation with acetone before applying the heat shrink tubing. Be sure to heat the tubing beyond what is required to shrink it to ensure the melted adhesive wets the insulation. I try to squeeze the glue out a bit to make sure it's hot enough. The only negative I've found is that the tubing feels a little sticky after shrinking and once it cools down it never feels like it's fully cured.
