Lol if the guy using the torch actually had it on the right setting and used it properly he would be done in 4-5 seconds, 3M just being stupid now

I still go with the heat shrink - mechanically better. All you did here was show that a cold shrink can be put on a few seconds faster.

Should use blue flame, for fast curing

This was a joke. That heat shrink could have been applied in half the time and with high quality.

I'll just leave the one comment actually pointing out that there are specific applications, areas or atmospheres where you can't use an open flame without risk of injury or damage to property.
The comparison here is mostly for final result. The timer was indeed useless, but the product looked sound.

Highly likely for the product to not be for personal use. Think more industrial applications.

Deceiving advertising, let me show you how to do the heat sink in 20 seconds tops

Never been impressed with 3M  adhesive tapes applied to LED tape runs either, hopeless adhesive qualities!

How tedious though. And all that plastic waste. Meh.
