Not so much, no. 😒 95% of all my trailer wiring troubles have been a direct result of lazy manufacturers using them instead of the proper product. Heck, even if you think they're working right, they likely aren't. I've brightened the lights
on 3 trailers just by getting rid of them. In contrast, I have NEVER had a crimped and adhesive heatshrink connection go bad, and never will. I caught the wiring harness on the car trailer once, snapped every damn wire for the taillights, didn't pull one connection apart.
That being said, I don't advocate $5 crimper/stripper combos, either, but that's a different rant.
