PONFY 150PCS Heat Shrink Bullet Connectors, Heat Shrink Female & Male Connectors Bullet Terminals, Insulated Waterproof Marine Crimp Automotive Connectors Wire Splice Connectors Kits

Good quality and every size I need, should keep me going for years.

Wiring for a trailer. Connectors work as design but time will tell if they will last. If compare to the ones from auto part store. They look cheap. But, great price and amount you get.

I seem to have the opposite problem of many: The heat shrink on my connectors is slow to act, enough that I initially thought it wasn't working as other reviews have described, but after a few extra seconds on the heat gun, it finally shrank, and honestly, LOOKS terrific!Only issue.. it shrank so much that inserting the "bullet" end of the wire is almost impossible, and I've had to cut two ends off already when I couldn't separate them once I finally got them inserted. Sort of defeats the whole purpose of the connector..... I might as well just use a butt splice instead because once the heat shrink is squeezing the female end, there is no "quick disconnect" possible.
