Quick Splices?

I dont like them, have seen them everywhere in cars. Under hood,dash and back of vehicles.
They fail. They promote corrosion.
I have a few in my terminal kit, in case i need a quick repair. Guess i should just chuck em. As i would have to do it right anyways. Never did use them.

had to do a service call to rescue a “professionally” built hot rod, ring terminals werent properly crimped on ignition switch. So not every type of connector is foolproof..
