I suppose it's somewhat satisfying to shrink it.
What's incredibly aggravating, however, is making a multi conductor cable up and crimping the last terminal in place, THEN noticing that lone piece of shrink tubing that you forgot to install on one of them sitting forlornly on the bench staring back up at you.
It is inevitably, of course,
juuuuuuust a bit too small to slip over the already installed termination.
Been there, done that, all too many times. And if you triple check, somehow a piece will fall off or jump through a wormhole in the short time that passes between you verifying it's there and affixing the terminal.
