What I did not like: the honest cons
Chanzon 3:1 Ratio 2" (50mm) Heat Shrink Tubing - Marine Grade Waterproof Adhesive Lined - 4Ft Roll (1.22M Total Length) Black Poly can disappoint if the size, setup, compatibility, or upkeep does not match your routine.

The other downside is that Amazon listings can change. Bundles, accessories, colors, prices, and seller options may shift, so check the current product page before you buy. I would not treat any review as a substitute for confirming the exact version being sold today.
