Wirefy 200 PCS Non-Insulated Butt Connectors Kit - 24-8 AWG Crimp Wire Connectors for Automotive, Marine & Electrical Wiring - High Conductivity Copper Splice Connectors for Secure Wire Joining

I'm very happy with these uninsulated butt connectors. They look and feel to be of good quality. They are thick walled and have tapered ends to make inserting the wire easier. The price is great for the quality you're getting. They are easy to handle and crimp. You will need some good quality crimpers with long handles for leverage and that's a good thing because these form a great connection when you use the right crimper. After using the proper size butt connector and only crimping once, I was not able to pull the wires apart. If you want a good quality uninsulated butt connector, that will form a great connection, are easy to handle, and will make a good long lasting connection, buy these and you won't be disappointed. I will definitely buy this again. I have used other uninsulated butt connectors that cost twice as much as these and these are just as good as them. I highly recommend them.
