Review on NTE Electronics 47 20906 R Shrink Tubing by Antoine Scisson

please note I got this purchase for nothing because 3/4" is the AFTER shrinkage measurement. I needed one 3/4" heat shrink BEFORE it sat down. I got my 3/4" measurements from my other heat shrink that works (which hasn't shrunk). I think I need 3/8" heat order shrink if it has a 2:1 shrink ratio, if i want a 3/4" heat shrink tube (measure before shrinking) they should clearly state it here.
