These things just make so much sense. The one thing that I would suggest to you is to consider the environment and heat gun you use… meaning, if you are using a large heat gun around a lot of wires be very careful. It took a little longer than usual to melt the solder. A smaller heat gun might have been better

They hold very well in moisture conditions

They're very easy to use, with a heat gun that is. But if you do your own wiring say on a boat trailer, or in my case an atv they're very useful, definately recommend

That shouldn't even sell the "squish" butt connectors anymore. These are the best. You'll want to get one of those little torch lighters and keep it with these.

Ordered it on a Sunday had it Tuesday.I do custom offroad lights on all types of vehicles. Live using these solder and seal connectors.

Buy them......It simplifies soldering with ease. All you need is a decent heat gun, slide the wires in both ends and heat until soldered and the heat shrink activates.

Tried using these because the listing stating that the solder would melt faster than the ends. This is absolutely not true. The heat gun actually burned holes through the side exposing the bare wires before the solder in the middle would even begin to melt.

this is not that great compared to other i have bought and used.
