200pcs ILamourCar Heat Shrink Butt Connectors Terminals - Waterproof, Automotive Marine Grade Electrical Terminals, Crimp Butt Splice Terminal Kit, 10-22 AWG Wire Connector Kit(3 colors 3 sizes)

These are fantastic connectors!As a hard-core critic, I find absolutely nothing negative about these connectors. They work flawlessly with a hot air gun. If you get too close, you'll melt away the center area over the copper.DON'T use a hair dryer! (if you're thinking about it)The only improvement needed is THAT BOX that holds them! It takes a pry bar or large screwdriver to open the damn thing. I'm serious. I considered throwing it out.

Good product

They work.....
